No, you really can't say that for almost any field. Money management and poker tournaments are about all I can come up with. In any competitive field with a quantifiable scoreboard, you could take the data, extract from it means and standard deviations, and say with x% certainty that one player is better than another. In money management, x is never very large. It's so small that you can't reliably say that anyone is better than anyone else, in fact the overall distribution of money managers isn't much different from what it would be if it were all chimpanzees selecting stocks with darts. In basketball or chess, x gets to pretty near 100.
