I don't think math helps us to win in gambling. Gambling is just pure luck. Math is helpful in terms of investments but in gambling, it does not help.
But i think that in some gambling games it is too much important that you must have some good calculation so as to play gambling in a good way.
Yup in some cards games the professionals will play calculated games. They can make the calculation and move the card but how and what is that calculations I don't know. I think making a good strategy is also called one type of calculation in gambling.
