It is really hard to explain the fact that luck does not exist and vice versa. In the games you listed, what can you count on if not luck? There is no strategy that can be applied. It's simple. You just press buttons and get the end result, which cannot be predicted in any way at all. I don't even try to understand it. I am captivated by the process itself. I enjoy the game and that's it. What else could there be?
Oh my God, i always think in terms of karma and luck, it's not true that luck doesn't exist.
There is chance, randomness and therefore luck that unfortunately you cannot control. It often happens to those who are lucky that chance is benevolent with them, clearly if on one side you get from the other, according to karma, you will pay for this luck
