I agree, math could only help you to win in gambling sometimes, but never always, luck is the most important thing that we should have in gambling, that way, we could assure ourselves that we could win and not worry about losing our money. But there are games in gambling which math plays a big role and I guess that could help you to win in gambling, however, avoid having too much confident on gambling.
I think you guys are not understanding the idea here.. It's not about math magically telling you what will win or how you'll win. It's about using math to your advantage and getting an edge in certain games. Statistics and all of that is a sort of math that you will use. Nobody can argue that you always need a bit of luck to win but yeah. You can use maths to your advantage.
