If you are a beginner/intermediate and looking to improve, I would take the common chess engines like chess.com/lichess with a huge, huge grain of salt, particularly accuracy %, and especially in the opening moves. While it is generally true that high accuracy is a more 'correct' game, there are many times moves will be marked inaccuracies that are neutral at worst, or, even worse in my mind, will give you perfect scores for accuracy when using an opening with 100% accuracy that is generally and statistically considered a losing opening. Lots of times, gambits will be regarded as errors/inaccuracies as well. It's important when you're viewing these numbers to look at why something was flagged and dig deeper, because if you blindly follow metrics, you will hit a ceiling where you absolutely will not beat more sound opponents. The other issue is that depending on the depth the engine is using, it may flag things differently.
