I don't know much about poker but sports betting definitely requires strategy, this doesn't mean that it guarantees win but if that bettor knows what he's doing then losses can be minimized.. casino games on the other hand has no strategy whatsoever that can be used to make profit... chasing profits usually ends up with big losses, so instead of fixing your mind on making profit just entertain yourself
Entertaining yourself via gambling is interconnected with chasing profits. Even if you're playing with small amounts, you can still win a fairly large percentage — and yet still feel unsatisfied. That’s because your brain starts thinking about what
could have been if your deposit for that bet had been larger, and how much you
could have won. Then you begin imagining how you would spend that potential win, and those thoughts are so tempting that you end up increasing your stakes, trying to catch the same percentage gain you’ve already experienced. And that’s when you lose — and loss is never a foundation for good entertainment.
