even if you grant the numbers Sklansky makes up, that isn't proof (or even a decent arguement) that mathematics is useful.

All you have done is shown correlation, not causation.

For example, maybe people who have no social skills do math and do poker well. Doesn't make math useful for poker. Nor does it show that doing math (ceteris paribus), would make you a better poker player.

So maybe non-mathmaticians arent the only ones falling for fallacies.
