I do not think that using math or other predictions you can win in gambling, and especially in roulette. There everything is designed for pleasure, not profit.
Me too, i don't think that math could help you win in gambling but it will be a help in making you decide on how much you will use as a bet to keep on playing longer and how much you will keep if ever you win. If you are good in math you can use it as a strategy in some ways if ever you have an idea on what strategy it is, but you can't use it as a prediction to win in a game. I don't think that gambling was just designed for pleasure cause most of the people risk their money even if there is no assurance to win to try their luck and earn more of what they have. It's just that gambling is not profitable in a long run.
