~ Luck plays a big role in gambling, no doubt about that. But we shouldn't forger that it plays a different role in different games. Some games, such as dice, keno, plinko etc, are purely luck based, while others, like poker and sports betting, require some skills in order to be successful. You can still lose in those games because of bad luck, but there's a good chance, not a "little chance", like you said, that you'll be in profit in the long run, if you possess the required skills.
You're right about this mate, not everyone has the luck of a thing in common, and not every gambling comes with a luck believe, some just need your intellectual skills and reasonings, it is understood that we have lots of games around the world woth their different means of engaging them into play, same is required that a gambler should understand the type of game and it mode of engagement in other to drrive something beneficial out of it, we advise one play a gambling game he's good at just in other to exercise expertise.
You still depend on luck in games like poker, and all poker players know how it feels when you have an Ace high flush and someone has a full house, or worse,
you have a full house and some has four of a kind. But such things happen rarely, and most of the you win with just a flush, let alone an Ace high flush. And, right, practice is important for playing a game of skill, while for purely luck based games it's absolutely irrelevant.
