It really does appear pointless trying to build strategies to enable us win consistently for a game that is tagged a game of luck but have you wondered that people seeing that there are others who are making it happen gets motivated and try to replicate that too. Strategies does work even for the game of luck so it is better to have that strategy and build for yourself an advantage than just trying at random often and not having that chance while you keep loosing your funds.
You have that strategy built; develop it to work for you just like others have their own too, but that still does not change the fact of a game of luck turning into a game of skill. In a normal scenario, there are chances of winning a game being increased based on the type of prediction skill that the gambler has before luck can now come into play, but for games which use RNG, it's all based on luck, and the only skill one should need at that point is the skill to make their bankroll last longer. The longer you can stay with the little money you have, the higher your chance of winning.
