Buboard may be assuming that performance is greatly influenced by skill and that skill is learned rather than innate, leaving a 'string of failure' in the learning process. Probabilistically, this is roughly that skill-based success is a coin with highly biased initial weight for failure, and learning changes the coin's bias. I do not care to speculate on how success actually works; I'm quite sure it's more complicated than I can fit in a comment.
