I don't think maths are able to help gamblers to have a higher win chance on all casino games, I think the only casino games that could give better advantage to gamblers are baccarat and blackjack as card counting strategy could be used, but nowadays casino will reshuffle the cards before using up the full deck, and it have became harder for gamblers to do card counting.
I definitely agree with you my friend I this regard that math can never ever help a gambler to win the game and it is really a truth that math can never help the gamblers. It would be a big blunder from ones side to say that math is something helpful in gambling because people who are good in math also lose games in gambling whenever they come to casinos to play, maybe in bigger ratio than other people who have little knowledge of math because gambling is depending upon luck all the time.
