This happens for a big reason, new poker players start playing inspired by big names like Daniel Negreanu, Phil Ivey, among others, and there are many videos teaching how we should play poker, how to play in position, or value hands, so with that, they start playing believing that if he does everything right, he will become a Daniel Negreanu or Phil Ivey of poker, but that doesn't happen, because the bads are there, and even if you play your best poker and choose the best decisions, that doesn't guarantee him anything in poker, and that conflicts with what he learned in the videos, and they start blaming RNG and talking about fraud.
So to answer the question, new players often talk about cheats in the game, as they don't know the nature of the game, but not all of them are bad.
The only thing missing is more videos and content related to this side of poker, which most of the time is not shown.
