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 think that everyone understands this, even those who deeply believe in something supernatural. But the main goal of prayer is not to achieve a result due to something supernatural, but to achieve psychological calmness. This is important for those who play for big money and are worried about the result.
