it depends on the game
some games have a skill component
other games like Poker are way more about skill than about luck
not all games will be 0% luck 100% skill / 100% luck 0% skill
some will be a mix like 80/20 or 60/40
Right in skill based games you can turn you luck into your side by playing skillfully and winning the game.I have seen players turning the whole game in Poker with normal cards against good pairs by their mindset so there are skill based games also.
definitely
Poker is a good example for a game that mixes skill with a strong luck component
chess is a good example for a skill game with a really weak luck component (the only way to be lucky in chess is if your opponent makes a mistake)
Poker is also a combination of experience and the ability to read others because if you can read other people's emotions, you can also sort of read their cards, though I don't know this game very well, but this is what I've noticed, so if you're very experienced on this, you have an advantage even if you get unlucky with your card picks. Chess was an overly broad comparison; instead, consider slots. Slots are entirely luck-based, with no strategy involved; if you get lucky on those spins, you will win, but most of the time you will lose.
