Luck isn’t even a betting strategy, so what are you talking about?
A strategy is something you follow because you believe it gives you a better chance of winning. Your strategy may change from time to time, but there are certain games where, no matter what strategy you use, it won't have a positive impact since those games have a house edge. Sure, you might win in the short run but lose in the long run. However, for the excitement of gambling, it's great to develop and adjust your strategy along the way.
For you to claim something is a strategy, it means it's backed up with facts in practice and a lot of testimonial to it working effectively. And if so far no one has gotten such strategy to always win gambling games, then we wouldn't say we have a strategy here.
If we are to use the word strategy, is the personal development strategy. Which is don't bet more than your budget. Try to flex your memory with the game, but don't put all your hopes in it, so it will not mess with your peace of mind when the game doesn't go as planned.
Have your mindset strategy, where you play for the best, but when it doesn't go as planned, you walk away. Learn to maintain your peace of mind, don't get depressed over one bad game.
As for luck in gambling - I feel once or twice luck falls in. It's just like spin games when you win a reasonable price. You can't say there is a strategy to winning from spinning games? It's just luck but you can't carry luck to every game. Flex your intelligence
