Every winning in gambling is all dependent on luck, this has been the case for decades whether online or physical gambling.
When you find that you are lucky on the day you play, for sure no matter what games you play in the casino you will win and you will go home with money, the question of luck is that there will be no problem when you take out the money you won in gambling platform you played on? because this is where there are often issues, to be honest.
yes indeed in the science of gambling, luck is the main thing and the strategy that brings us closer to that luck.
sometimes a gambler forgets this knowledge and just bets without thinking about the strategy he has to calculate with mathematics. but almost all gamblers always use a strategy to gamble in one of the games to get profit or victory. although in the end it is luck that decides, but if you are good at calculating betting strategies, it will be closer to the luck you will get.
I agree about the luck but for the strategy? I think it depends only on certain games. It can be applied on poker, blackjack, on some other card games and also in sports betting. For someone who is serious about winning and making a profit then there is no way they can forget adding a strategy to each of their games but there are some who just wants to test if how lucky they are, and there are newbies who don't know if what strategy is good to use so they just play the game directly.
Other than calculating the strategy, I think it's best to also calculate the odds or our chances of winning, so that we can decide if it's worth the risk or not.
