This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Jaedong (Lee Jae-dong)'s outcome attributable to any origin.
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 Creators / artists, Jaedong (Lee Jae-dong)'s starting-advantage total is at the 95th percentile. Separately, their built or converted leverage total is at the 90th percentile.

Evidence summary
Jaedong grew up in Ulsan, South Korea, during the peak of the Korean Brood War esports ecosystem. His parents' purchase of a computer in fourth grade introduced him to StarCraft, and his arcade background from third grade built his gaming foundation. He joined the Korean professional gaming pipeline at 16, debuting with Hwaseung OZ in 2006 and winning Rookie of the Year. The Korean esports infrastructure — team houses, televised leagues, and KeSPA ranking system — provided an elite performance pipeline. His prodigy-level Zerg play, particularly his mutalisk micro and 81% ZvZ win rate, set him apart. He won five premier individual league titles by age 26.
