You're very right with your opinion about gambling when it comes to "luck" and "logical". When it comes to gambling, the biggest factor that determines winning is the "luck factor" and that's why som many people still end up not winning despite their high level of logical and strategical approaches. There's no doubt that in gambling, you needs to be very logical and strategical to increase your chances of winning ahead of others but when you're not lucky, you might not even win at all.
There are many gambling games and for some of them, you need to be very logical in other to be able to win but the bottom line is that you'll still need luck to win big
If they realize that in gambling, they really need luck, they should be able to see that getting luck will never be easy because someone will not know when their luck will come. Even though he is close to winning, if he can't win, it means he still hasn't won, and his luck won't come when he wants it. And even though the gambling game is a logical gambling game, they still have to have luck to be able to win because winning is the ultimate goal of someone playing gambling.
But if they aim to gamble just for fun, it's fine for them, and they won't try too hard to win. They know that if the gambling game is logical, but they are unlucky, they will not be able to win. So all gambling games are logical to win, but the problem is that we need luck to win.

Well in card games, being good matters because you've gotta play your cards right, read opponents, and make smart moves. Sports betting is like a puzzle yes like analyzing teams, players, and stats helps make better predictions. It's about finding the sweet spot between skill, analysis, and a bit of luck.
That little bit of luck will determine whether they can win because after all, in gambling games, we need luck. If their skills and analysis are good, but they haven't been able to get lucky, they won't be able to win. They might be able to win later, but who knows when they will get that victory. And if they continue to gamble, instead of winning, they might lose.
