Grandmaster Blunder vs Amateur Blunder

If a Grandmaster blunders is it higher rated and stronger than a blunder by an amateur?

I ask because I create fictional games between chess players from the past and present in a new genre of chess fiction I call the chess time machine.

I was lucky enough to have the chess YouTube king Agadmator feature one of my chess time machine fictional games Bobby Fischer vs Garry Kasparov. His followers said the game was not believable lol 😂 because Kasparov wouldn't blunder like that 🤔

So is a Grandmaster losing to mate in one less of a blunder than a 1400 elo player blundering mate in one?

I mean when Grandmasters play each other and one of them wins the other loses right? That means the losing GM has blundered. I know some people will not accept this perspective.

I mean, they still blunder. But most games are decided by mistakes or even only inaccuracies... as far as I'm concerned. For example, losing a pawn or two that lead to a lost endgame.

@TonyKoIarek okay now we are getting to the good stuff, what is the difference between a blunder and an inaccuracy or mistake that leads to a lost game?

Ok but Bxh2

@Megadoggah Agadmator chose the most unrealistic game I had many they were created by AI and I told him their were better examples. I guess it made for a better video to use one that seemed weird .

It depends what you mean by "blunder". In general I think the better the two players, the likelihood of a smaller mistake being punished increases. Put it this way, if I played against a GM here and said GM hung their queen I either wouldn't see it, or not take it because I would assume it's part of a strategy I can't see. If two GMs played against each other such an error would not go unpunished.
