Gambling is both combination of luck and your skills, but decisively we win by chance. Your bets are placed based on your already gotten knowledge as you have already said, of which you stake on those predictions within your risk tolerance level and accept any outcome of your bets.
My take on this OP, is gambling isn't fun as well as either you lose or win. We all just take part in a probability game that is uncertain, we accepting this fact shades us from Ill feelings of which we keep betting nothing more or less.
Of course judging from normal Human perspective it won't be fun if don't all lie to ourselves, we all know and accept lose as part of game so it becomes fun when we lose then if am to put it this way. In essence gamble responsibly with your set rules so as not to reach a stage you become emotionally unhealthy and then the fun dies off the game.
Sometimes gamblers' thoughts also make sense. but some gamblers are aware that they are betting and have the hope of winning. Even though the results depend on luck, gamblers still bet happily.
if there are gamblers who still think gambling doesn't provide fun for them. I'm sure the gambler is under pressure from losing a game that is increasingly making him frustrated. However, the impact of gambling varies for each gambler. and their responses are also sometimes unique.
Gamblers' wins and losses have no long-term effect. Because a gambler never stops at a win or a loss. But there are some gamblers who gamble with the money they cannot afford to lose. Gambling becomes no fun for a gambler when he bets such money and loses. It is normal to be depressed when a gambler loses his money. Gambling is considered fun by those who accept loss and win. And gambling does not bring joy to those who strive only to win. A gambler must be prepared to accept both profits and losses. If there is no high expectation from gambling then losing in gambling will have no regrets.
