We win by chance and not luck, every gambler wins because of the chance present in the game, its not being lucky. It doesn't matter whether you have won for a long time or not.
Chances or odds determine the possibility of your winning, but you only win if you are lucky enough for that because the results are randomly generated and aren't influenced by anything else. It means how consciously or how much you are experienced in gambling got nothing to do with your winning chances.
You won because your analysis and prediction work and you were ready to risk the amount you risk because you know two possible outcome win or lose, will you then say you were lucky for the winning?
If there are two possibilities, winning and losing, and you are winning when the result is ought to be randomly generated, what would you call that? It's luck, if you are unlucky, you lose.
In essence there is no game of luck, I know some gamblers believe luck happens, if luck exist what's the need for predictions, decision or analysis before we place our bets.
You don't do analysis or anything when you are playing luck-based games. How can you do analysis when you are playing in a slot machine? You can't do that, all you do is decide the amount you want to bet and press the button.
For me luck is just an illusion we are wired to believe. Gamble responsibly, discipline and moderation is needed and appropriate risk tolerance that's all. No need to overstretched it.
Responsible gambling is important, no doubt about that, but I don't agree with you that luck doesn't exist, if it didn't, no one in the world would manage to win life-changing amounts of money from gambling that too with very small bankrolls.
