The short answer is "you should not worry about it".
The long answer is "an experimental method developed by chess.com to compare your moves to an engine and convert all your moves in a game to one number".
what is Accuracy?
Sort:
How accurate was your move? If u play theory like those book moves in the beginning of each game u play at 100% and when the theory ends then your moves are rated great-good or then mistakes and blunders. If you play the best move in every position you get better accuracy so the higher your score was, x/100, the better you played your game based on your opponents moves of course.
Accuracy is a relative score against stockfish. In the long run, the higher your accuracy, the more games you will win.
Accuracy is although like an average. If you play perfect but blunder a queen you will likely loose while your accuracy will be higher than that of your opponent. Rising through the ELO ranks myself I noticed that in a lot of games the position is that complex that both you and your opponent does not see the idea behind the position. You both have a low accuracy but this factor is not so relevant. You played and think like (bad) humans and the computer idea (to which your game is compared) is not so relevant.

Accuracy is how good your moves are, in relation to the top engine, Stockfish. If your moves are brilliant, great, best, excellent, or good for most of the game, your accuracy is given a high value. If your moves are inaccuracies, mistakes, misses, or blunders for most of the game, your accuracy drops to a lower value.
Accuracy is also a good gauge for the level of complexity you're operating at.
Lower level players cannot manage much complexity and look at individual pieces and moves, maybe a single line. Then you start going deeper and deeper into chess until you understand the full complexity of what's happening on the board.
It's like getting to know a woman, a one-liner doesn't get you far. Then you have a conversation, it gets complicated, and in the end you're tasked with having to understand her entire life and mind. Crazy.

What does this have to do with accuracy? In my opinion, exactly nothing.
Sometimes I let the site analyze my games. It gives a certain accuracy. But I don't know what it means. My ELO is under 500. My accuracy is between 29 and 65. I don't think there is a connection in accuracy and winning and losing in my games.
So what does accuracy mean?
