I do believe that mathematics help affect gambling games. One of the reason is the computations of betting and the winnings. If math does not exist in gambling then gamblers will find it hard to compute their moves and their winnings.
I want to know that why you believe that having some knowledge of mathematics help a person in gambling games. However I can prove you wrong because if math was of some importance in gambling then the people having a sound knowledge of math would have won every single game they play but here in reality the case is totally different as they still are losing.
Mathematics can help you analyze your game and even determine amounts that are right for you to gamble per every game and what you could expect to win but mathematics will not contribute to your winning in any way because most gambling games out there aren't based on logic and mathematics is limited where there is no logic.
