Of course, luck is a mental peace where if you bet on gambling and lose, you tell yourself that maybe you were unlucky and that's why you lost the gamble. However, it is okay that sometimes luck does not favor you, but for those who bet repeatedly, luck is not important because there is a kind of greed inside them that makes them bet repeatedly. If you lose by placing consecutive bets, you should not blame luck in any way.
Luck is peace of mind, I believe. Because when we lose in gambling, we can blame it on luck and feel peace of mind. This is true. But there is no denying that most gambling is based on luck. Slot Machines, Lottery and Roulette are completely based on luck. I don't think skill has much to do with it. We don't find people here who have gone to a casino and tested their luck on a Slot Machine. However, some gambling requires skill and experience. Skill and experience are required in various card games and sports gambling. These are not always based on luck.
