I think maths cannot help you win in gambling because gambling is a risk and you take a lot of chances that you only think positively that you can win in gambling especially in card games. In roulette game i cannot say if maths could help you in gambling because you play it using a machine.
What do you mean by playing with machine? If you are playing in an online casino then yes you are playing with a mere machine. If you are playing in a live casino then yes it is a machine as well. There is almost no difference in it. Wether you are playing with a real person or a machine, math is not going to help us win but just increase odds to calculate our chance to win
