If you have said so it would have been best for you to come up with your proof to back up with what what you have said. I can agree with you that online casino more players who gambles to make profit because in online gambling players can easily stake games at anytime, my thought though. But I don't know how you get to know that physical gambling is more of players who stakes for fun,  I won't accept this  because I know both online gamblers and physical gamblers plays game just for the sake of making profit.

The truth is that no one can take note of why gamblers that stake in physical gambling house, what is their reason for gambling either for profit or fun. I think op is just exaggerating just on his thought concerning gambling. This is a opinion without any fact.
