That's just it , gambling is meant to entertain not any means of getting rich quick and easy , that's why most folks with the getting rich through gambling quick mentality, usually get themselves rekt in gambling, because to gambling is for fun and if you are lucky to win take the extra bucks you won as a bonus to the entertainment, that's why we shouldn't put much at stake then rather that we can risk and we can easily recover when lost .
I agree with you that we should see gambling as entertainment that we pay for, so that you can understand how much you will let go on having fun without expecting any reward. If after the game, you won your bet, you should see it as a bonus to appreciate your patronage. Maybe, that will help you discipline yourself and limit your losses. However, some gamblers are alwys carried away when they are gambling, and if they don't exhaust their bankroll, they will never stop.
Yes, that is a good idea and perspective on gambling, it should be as you said that a gambler should see gambling as a place of entertainment that must be paid for, just like other types of entertainment such as going to the cinema or to tourist attractions that certainly require some money as a fee that will be exchanged for pleasure, at first glance this looks like two different entertainments but a gambler should and should view gambling as they view general entertainment, because that way they will not put any hope in winning.
In the sense that as you said that victory should be considered a bonus that comes occasionally after the pleasure we have received, but it turns out that the fact is not like that, right? yes as you said that the majority of gamblers get carried away, but in my opinion from here we can conclude that from the beginning gamblers come not with a perspective like when they see general entertainment but they come because of the thought that they can multiply their money in gambling and clearly that is wrong thinking.
