I genuinely have some concerns about what you're saying - I believe you need to try to look at the stats critically or conservatively, without the influence of poker marketing itself to players.
You're saying that 5,000 games is enough to determine your overall winrate, and yet every 5,000 games of yours has been different: from game 31,000 to 50,000 (a recent 19,000 game streak), you are down.
Either this should mean you are a losing player, or it means 20,000 games is not even nearly enough to draw a conclusion. Be careful about having it both ways to suit you: that is confirmation bias https://en.wikipedia.org/wiki/Confirmation_bias.
Let's say, I wish you the best of luck, and leave it at that.
I said after 5,000 games your results will begin to closely depict your winrate, not that it would 100% be correct. Variance can easily cause a winning player to have a breakeven stretch.
On top of that, you seem to be suggesting that the variance in my ROI is somehow attributed to an inherent "luck" factor of poker while ignoring the fact that the sample size ranges from micro stakes up to high stakes poker. My winrate is obviously going to vary between stakes because poker is a game of skill and the higher the limit, the more skilled the player pool.
FYI, it's also quite annoying to throw wikipedia pages explaining common psychological biases at me when you've already stated that you are basing most of your conclusions on "assumptions" since you aren't well acquainted with the subject matter. I'm well aware of everything you're warning me about but you also seem biased against poker. I've shown you a sample of over 50,000 tournaments. That's over 1.5 MILLION hands of poker. It blows my mind that you seem to be keen on ignoring empirical evidence and mathematical analysis here, but if you want to ignore that, so be it.
