Beat stockfish

If every single person on earth played stockfish once, will there be a chance that one of them beat stockfish (no other help allowed, just the player)

Maybe, but I am not sure.

I don't think that is possible...

no way

to draw is already hard

ok

i played stockfish against stockfish and Stockfish as black blundered (Mate in 21 though)

There are some people, though a very small portion of the chess community, that purely only play against engines and study them a lot. 
If you had some sort of simul where the entire worlds population all played 1 game against the most advanced version of stockfish, and it was a classical game so they all had ample time, there might be tiny handful of people who MIGHT win, if they get the perfect position, purely because they understand how to beat engines.

Also there is a small chance one of the top players like Magnus might snag a win because they are much higher rated.

However the chance of all this going the way i described is very small. in all likelihood stockfish would win every game. It's like asking if every 1000 rated player in the world vsed Magnus would any of them win. There might be a slim chance, but the chance it would happen is tiny. the difference between a 1000 rated player and Magnus Carlsen is just too big.

Thats the same difference between Stockfish and even the highest rated GM's in the world, nevermind the rest of the human population.

Even with billions of people playing against Stockfish, the odds of someone beating it without assistance are so astronomically small that it’s effectively zero.

Stockfish rating vs magnus rating is much higher

Do you like black man?

Do you like black man

ok then is even beating stockfish humanly possible? Or is there an engine that calsulates so well every move is ACTUALLY the best move out of the thousands and thousands in any position?

Its humanly possible, as engines arent perfect, and despite what you said, they don't pick the best move possible in every position. they mostly do, but not in every instance. Butthe chances of a human winning under a default position is very low. you'd have to get a great position out of an advantageous opening which takes advantage of the engines weaknesses, and even then your chances of winning are astronomically low.

In the far future there are predictions that an extremely powerful super computer will solve chess, but it will take a long time. as it is now, chess isn't solved.
