Sure thing math helps when gambling, maybe not the actual math but being number friendly is a huge advantage
Not always because there is nothing one can do in dice gambling with their maths since under/over have equal chances. But I agree that maths can be helpful if someone is doing arbitrage betting or trading of odds because that can help you quickly realize how much you should bet on which event and what's the best time to do so.
Dice game is different, it's a luck based game so all you can do is just rely on your luck to win.
You might win with some little analysis but with the house edge we know that our chance to win is very low and no strategy that will work in the long run. Better use your skills in math in skilled based games as for sure you can benefit from your effort and might develop yourself to a profitable gambler.
