This is a bounded inference from the current annotations—not a claim about private effort, merit, or the percentage of Junior dos Santos'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, Junior dos Santos's starting-advantage total is at the 38th percentile. Separately, their built or converted leverage total is at the 6th 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
Dos Santos grew up in extreme poverty in rural Brazil, raised by a single mother after his alcoholic father abandoned the family. He started working at age 10 and trained in capoeira as a teenager before beginning formal martial arts training at 21. His natural heavyweight power and athleticism, combined with training under Yuri Carlton (BJJ) and Luiz Dórea (boxing), and later mentorship from Antonio Rodrigo Nogueira, propelled him to a stunning UFC debut knockout of Fabricio Werdum at age 24. The UFC/MMA boom of the late 2000s provided a structural wave.
