You need to understand that magic and gambling are two very different things, I have a magician friend and he often bets on online gambling and often loses, in fact he is a magician, quite famous in my area, So as far as I know, magic tricks require practice, skill and most importantly hand speed, this is all done with practice.
For example:
the magician guesses the card chosen by the audience or the magician guesses one of the hidden objects or how the magician does other tricks, maybe you can watch on YouTube leaks of them doing magic tricks.

Magic games that have been studied and practiced, gambling games that have not been studied and not practiced, magic requires hand speed, gambling does not require hand speed, so magic cannot be played in gambling.
The proof is: there is no magician who can take all the money in an online casino, especially now on online gambling sites, if a magician managed to do this and always win at gambling, the magician would definitely be rich, that fact doesn't exist.
