Indeed we need strategy while gambling and most often math will be included on such strategy. But believe me, there is no strategy to guarantee that we will win the game. That is why some people says that math won't help us to win the game.
Math could never be the way on how we could win against the house in gambling, because math is just play a small role in gambling, and that is when we are calculating the bets that we are going to make each to know if how many rounds we could make, and if you are going to think that MATH could helps you in gambling, then I suggest you not to gamble anymore because you are just going to lose all of your money.
