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.
I'm not sure about that, because if most religions don't condone gambling, then how come gambling itself can grow in so many countries with different religions and cultures as well?
I would probably believe if, most religions forbid gambling then gambling would not grow. But what happened is very different from the reality because even gambling has entered the realm of business which of course there are still many religions that do not prohibit gambling, right?
Therefore, when they pray in gambling then maybe their religion doesn't forbid gambling, so there is nothing wrong about that because they have different beliefs too and we will not know about their religious affairs.
