There was a study done on this kind of mentality. Researches invited pairs of players and before each game flipped a coin to designate one player rich and the other poor. The rich player was then given more money and an easier set of rules. At the end of the game they interviewed the player that inevitably won, and in all cases the players reported that they won because of key decisions they made while playing. Not one mentioned they got lucky with the coin flip.
