Obviously, you know you are right and he is wrong.

Maybe if you explain to him that scapegoat theories like these are created by losing gamblers so that they can blame someone other than themself for the money they lost. And since everyone (except for a very small miniority) lose at Blackjack, these theories become "fact" over time because of course everyone would be a winner if only the guy at third base knew what he was doing or those damn kids would only hit their 16's into a 10.
