It is best to look at the success in gambling over the past six months or a year and it will be clear what to expect in the next six months, I also agree that a player cannot just change, if before that he was losing all the time, then most likely he will continue to lose, miracles do not happen. We are unlikely to ever know the percentage of successful players, if they show us some statistics, it will be clearly overstated, because it is profitable for the casino for you to think that you have a better chance of winning.
This is what I had in mind before and I ran this experiment for 1 year with a division of 2 periods, and what I got was the percentage of losses in the first 6 months was much higher than the wins, and the next 6 months were just closed 2 months ago, there was indeed a slight decrease in losses but in those 6 months I didn't do much gambling activity, so you could say the results were the same. Lol unfortunately I have deleted all those notes so I can't share them here, right now I don't want to do the experiment because I'm worried that doing those things continuously will affect my mind and it's better to just do it as usual.
