Is it that the definition of gambling being fun is mostly applicable to moments when you're winning.
Most people think so and I do believe it is natural because it is hard to say that we are having fun while we are losing.
For me, having fun is combination between enjoying the game that I like to play plus winning it.
I have to say that even if I accidentally win something on a game that I do not like, I cant really feel the fun.
When it comes to your title "losing = addictive", I'm not fully agree because I still believe that addiction comes from both winning and losing.
That's huge, there is no joy in losing or I mean anyone will never feel happy when they lose money in any case. But it is a fact that gambling is about winning and losing, but that doesn't mean that when you lose you have to be upset, because of course losing is part of the game. This means that I understand that a winning situation is fun, but for gamblers who understand the opportunities and are aware of the risks, a losing situation doesn't mean it will make them completely upset or emotional, because the goal of gambling for fun is not the result but the process of playing the game, or Simply put, you can get pleasure when you enjoy the game without thinking or caring about the outcome, whether you win or lose.
On the other hand, you say that when you accidentally win at a type of game that you don't really like, then at that time you don't feel the real pleasure, meaning I would say that you are a gambler who comes with the intention and purpose of enjoying the process. and don't make the results at the end of the session your main priority or focus. This means that every gambler has his favorite type of game, but there are some gamblers who do not feel significant pleasure when their winnings result from another type of game that is not their favorite game, because the sensation produced by their favorite game is different from other games, and they are gamblers who really come to just enjoy the process without caring too much about winning or losing.
