I think maths cannot help you in playing gambling because when you play you don't have to compute or get the formulas while playing gambling. All you need to think while playing gambling is whether you take the risk or not. But i think there are some gambling games that could help you in gambling like slot games and dice games.
With sports betting math can help to get rid of loss to some extent based on certain strategies. This won't be successful every time, because it gets successful results if the match has been going as we predict. Even a small change in the game plan that we predicted will end up in losing.
