Of course, gambling for fun means you don't expect any winnings when you play at the casino, you just enjoy what you do by gambling at any casino.
No heart feelings about the amount you lose when you gamble.
You have no other reason but to just have fun playing at any game provider at the casino,
I can't think of anything else besides what I've already mentioned.
Do you think gambling for fun exists?
Yes bro, it exists!
The only issue is that most people who are saying they gamble for fun are lying about it, you will hardly see people gamble for fun. I still gambled for fun on Friday at a physical casino, and when the result came out, I lost and it did nothing to me because I gambled with a ridiculously low amount that can't even feed me for a meal. That's the fun of it, you will start knowing them with their low wagering and the way they laugh at the result even if they can afford a big risk.
Basically, yes, I quite agree with your opinion that many gamblers camouflage themselves in the idea of "having fun" when in fact their purpose in coming is to seek victory and if you want to know whether the gambler comes for entertainment or not, then you can see how they react when they experience defeat, if for example they show an emotional reaction or response or even while uttering harsh words, then it is clear that it means that they are gambling not to seek entertainment but to seek victory, I can assure you that it is a fairly effective way to find out what their purpose in gambling really is.
On the other hand, gambling for entertainment never sees the results, meaning that it does not make the results the main priority that they must pursue, as you experience and what you feel where you are not at all affected by defeat, for me gambling for entertainment is when your goal is entirely to fill boring free time but that does not mean I reject victory because after all it is a fairly good result to be utilized.
