If you think that praying will give you better odds, you're delusional.
Most religions don't condone gambling so why the hell would they respond to prayers in gambling? That absolutely makes no sense.
But empirically there is no correlation - everything is mathematically determined and has nothing to do with your psychology, and the odds are stacked against you due to that.
Core gamblers are the type that is always difficult to persuade and are always the prayerful type, but they are also the ones with the highest probability of winning, the odds are always in their favour, and they are always prayerful, but their belief that gambling a small amount of money will make them rich overnight is a willful delusion. How do you expect to earn thousands of dollars with a single wager and prayer? They are extremely familiar with every bet, but the fact is that they need more money to obtain more money unless they are the kind to come across that unusual luck in gambling.
Coming to the prayer part, you know how we as humans prefer to hope when we are anticipating anything. Instead of tossing a coin, they would rather hope on prayer to determine their faith and mankind has always hope in God and hence, this may not be mathematically proven but it helps many people and eases their way through difficult times. Some claim that prayer works for those who believe; if you believe in stone, it may be your guide amid difficult decision-making and anxiety.
