If you don't want luck to disrupt your gambling experience, get into sports betting. The outcome of a sports event isn't always dependent on luck because it's not like a gambling game where you press a button and then wait for the RNG to generate the result for you to see if you were lucky or not.
In sports betting, you place your bets based on your knowledge about the teams and players involved in a game and you know their capabilities and abilities and how much skilled or unskilled they are, so your bet wouldn't be based on luck in sports betting.
I know that luck can affect games sometime, you will see a team losing that you expected to win and statistically, it was ahead of the opponent. However, this doesn't happen all the time.
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.
True, gambling is a combination of skill and luck especially when you are involved in the type of sports betting that does require skill and knowledge to at least help bring you closer to winning, but still in the end you will lose if luck does not come at the right time, meaning that no matter how skilled you are and have a lot of knowledge it will not work to bring victory if luck does not come at the same time. But this makes sense and confirms the reason that gambling is always about uncertainty in terms of winning.
Every gambler has their own perspective and goals in gambling, some come for entertainment and some come with the full intention of winning, all of that is up to you because you have the right to make whatever decision you want but on condition and note that you must really understand thoroughly what gambling is actually about, because in some cases usually someone who comes with the aim of making them do not have the ability to accept the fact of losing which makes them instead dominated by emotions which ultimately makes them experience a greater number of losses. On the other hand I understand that everyone does not like losing, but this is gambling which will always involve the possibility of losing, simply put if for example you don't want to lose anything then obviously it's better not to gamble, but if for example you still want to stay involved then obviously you must have the ability to accept whatever the risks are.
