If you want my opinion, many outcomes are just random or some maybe set to win after say U, W, X, Y... amount of attempts done and there maybe sort of a control too like allow A teams to win on first attempt, B teams to win on second attempt, C teams to win on third attempt (it is called doing business using mathematics, sort of a slot machine with odds set in such a way so that the house makes profit). In others words, a much weaker team will still probably win.
