This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Arvydas Sabonis'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 Athletes, Arvydas Sabonis's starting-advantage total is at the 51th percentile. Separately, their built or converted leverage total is at the 36th percentile. Other T2 profiles average 7.9 / 24 starting advantage and 12.3 / 25 leverage. Similar scores appear in other tiers, so these figures describe positioning—not a cause.

Evidence summary
Sabonis was born to Andrius and Milda Sabonis, a working-class family in Kaunas with no basketball tradition. Parents first enrolled him in music school before basketball at 13. His exceptional height (7'3") and the Soviet elite sports pipeline drove his rapid rise: national junior team at 15, professional debut at 16 with Žalgiris, and three consecutive Soviet league titles by his mid-20s. No family financial or domain advantage was documented; his early advantages were physical talent and the Soviet institutional sports system.
