The Animatrix is related to the The Matrix. As far as I can tell, they all take place in the same universe. But you don’t have to watch The Animatrix before you watch The Matrix Resurrections. You can watch The Animatrix before or after The Matrix Resurrections. Either way works just fine.
If you want to squeeze every possible drop of enjoyment out of The Matrix Resurrections then you should watch The Matrix Reloaded and The Matrix Revolutions before watching The Matrix Resurrections. However, I do not recommend that you actually watch The Matrix Reloaded and The Matrix Revolutions at all because The Matrix Reloaded and The Matrix Revolutions are (in my opinion) boring.
