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.
I agree,i think math can't help to win in gambling..In some ways math are applied like in playing card games but it really never give you the advantages to win in gambling.
True, math will not give us the assurance that we can always win in gambling. Math in gambling is just a way to predict the outcome of our game. Math can be used to manage our money as well but the end result won't depend on it.
