Sometimes it help in some games at casinos as long as you follow thr rule but most of the time its luck and it is always true in casino games it is usually govern with ones luck.
For me, math can help you in gambling. Why? Because the possible outcomes are computed or I may say predicted. Just like the dice, cards have already possible outcomes. It can gives what is the probability in winning or losing in some games offered in casino.
Also i think math can help you in gambling in analysis if your playing, it also helps you in a way how you plan your strategy using math approach.
