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 disagree because i have a friend of mine who uses mathematics analysis for the games that have numbers. He explore every digits or numbers that he saw and can be solve for and the answer will properly near to the result of the dice or roulette. Gambling is something needs a smart mind to figure out the things and make a move that can confuse the programmed computer.
