Maybe if you are playing a math based game then probably it can help you. Yet most of the gambling games are basically based on your luck or other skills like logical thinking. I think the author was trying to atleast relate it to math and did said that you will win using mathetical equation
Can you give an example of a math based game gambling? I have never seen such game so far, as what I have seen so far are just game with numbers such as dice, roulette and lottery but I think they are not math based games.
They are definitely not. Math is nothing to do with this. No matter how good you are in math. It can't help you to win in a game like dice which the result is completely random numbers. Many mathematician should have won or atleast try to win in a lottery if ever.
