Yes, maths can help you win at some casino games. Like blackjack for example. If the conditions are good for the player, it is possible to use maths to turn the probability in the player's favour.
You can beat dealer only if you count cards, but you will probably get kicked out of casino.
Maths could help you but not that much in sport bettings. Maths help you count the probability of some gambling like dice , roulette or mines. Cauuse their percent happen are 50:50. So you could find out how ricky you are playing at casinos gambling . In sport betting, you need to know more about Head to Head history, the form of that team . Much more things and it's complicated not like casino games.
Nonsense. Math can't help you to win dice roulette mines or any other luck based game.
Math is everywhere. Most of the games are based on math, you need to have a little basic understanding otherwise you may lose big. But luck would be the most important factor in gambling.
Actually if you don't want to lose lots of money you have to gamble only with money you can afford to lose, you don't have to use math for that. Btw what do you mean lots of games are based on math? All games are based on math.
