Athletes · Tennis · milestone at age 19 ·Field-leading
Selected age-relative milestone · age 19
Won World Championship singles runner-up in 1983 at age 19, World Championship doubles gold in 1987 at age 23, and Olympic doubles gold at the 1988 Seoul Olympics at age 24.

Born in Iksan, Jeollabuk-do, South Korea, Yang discovered table tennis in the third grade (around 1973) when her teacher recommended she try the sport. By her second year at Iil Girls Middle School, she was already showing exceptional talent. She rose to become one of the worlds leading womens singles players of the 1980s, rivaling Indonesias Susi Susanti and Chinas Ye Zhaoying. She won World Championship singles silver in 1983 at age 19, World Championship doubles gold in 1987 with Hyun Jung-hwa, and Olympic doubles gold at the 1988 Seoul Olympics, becoming South Koreas first Olympic gold medalist in table tennis.

Starting point

Born in 1964 in Iksan, Jeollabuk-do, South Korea, introduced to table tennis by her elementary school teacher in the third grade.

Current position (2024)

Retired table tennis player, works as a table tennis coach for South Koreas junior team in Seoul.

Where the conditions came from

Three sources, read side by side

Each is placed on a −1 to 3 scale from documented evidence, and the three are never added together. A combined total would rank Yang Young-ja against other people. Held apart, they explain why this path ran differently from another one—which is the only comparison this project supports.

The marble itself

What they brought

+2Tailwind

What capability, drive, or early skill is documented in the person rather than their surroundings?

Discovered table tennis in 3rd grade (~age 9) when teacher recommended she try the sport. World Championship singles runner-up at 19. Prodigy-level achievement in reaching world-level by 19, described as the only Korean player who could challenge Chinese players.

Where it was dropped

What they were handed

0Neither way

What money, family standing, network, or permission was already in place before the work began?

Father was a merchant (상업), mother was a homemaker. Six children in the family, Yang was the youngest. Rural Jeollabuk-do province during South Korea's developing era. Working-class family with no table tennis connections.

The shape of the track

What surrounded them

+2Tailwind

What place, timing, institution, or peer group made the next step available?

School teacher introduction at age 9 provided domain entry. Korean national table tennis system with structured training. Competed at Samsung Sports Center with national team coaching. Korean national pipeline provided elite competition exposure.

A −1 is a documented headwind, not a missing value; a 0 means the sources record nothing notable either way. Annotation confidence: Medium. These are analyst readings of what the sources record, not measurements of merit, talent, or effort. The twenty-two scored dimensions remain available inside the deeper research detail.

Yang Young-ja's leverage provenance

Each non-zero lever gets a best-supported origin, evidence signals, and confidence. Unresolved is the honest default when the biography cannot distinguish self-built, advantage-enabled, earned, external, or mixed.

Frontier geography (1/2)

This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Yang Young-ja's outcome attributable to any origin.

Luck is not a leftover score.

Structural luck, Encounter luck, Event luck, Outcome variance can change every arrow in the path. This successful-only dataset cannot observe the near-identical paths that did not break through, so luck stays visible and unscored.

Within Athletes, Yang Young-ja's starting-advantage total is at the 74th percentile. Separately, their built or converted leverage total is at the 83th percentile. Other T2 profiles average 7.8 / 24 starting advantage and 12.4 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Family context

Yang grew up in Iksan, Jeollabuk-do, South Korea. She was introduced to table tennis by her elementary school teacher in the third grade, suggesting the sport was not a family tradition but was discovered through the school system. South Koreas developing table tennis scene in the 1970s relied on school-based programs for youth athlete development, particularly for girls.

Evidence summary

Yangs introduction to table tennis through her school teacher at age 9 shows early domain proximity through the educational system rather than family inheritance. Her rapid rise to World Championship silver at 19 demonstrates prodigy-level talent. The Korean national table tennis system provided an elite performance pipeline. Her partnership with Hyun Jung-hwa in doubles created a complementary team that won World Championship and Olympic gold.
