Serral for example is the current best StarCraft 2 player in the world. They operate in tournaments where X players face off usually starting with 16+ players doing single elimination. He won 4 regional, and 2 international tournaments in a row. The odds of him pulling that off if the odds of each win where close to 50/50 would be ~1/(2^30) aka 1 billion to 1. Instead, he was heavily favored in most of these match ups.
