not all slots with high RTP are necessarily very friendly on your bankroll. In general, games with higher are RTP are always a better choice than the ones with a lower percentage, but if your game of choice is very volatile, you can go through many thousands spins before coming anywhere close to true RTP.
SourceI think that point of gambling is to stay the f out of true RTP

True RTP means a loss for a gambler. The closer to true RTP you want your output to be the more certain it is that you will exit casino with loss or 0.
Therefore, if i'm gambling i choose high volatile games with as big RTP as possible. That's the only way to win big. To feel emotions.
I do not pay any attention to the live RTP. It does not matter for me if someone who played before me win o loss.
