You should focus on basic checkmates and tactics, and strategy will develop too. You should also learn calculation of a series of moves, which I guess is tactics.
Hovering Around 400. What Should I Learn?

Lmao at least it's not just me! We'll get there, best of luck!
No worries. I would add as well that it looks like you are playing exclusively 10 minute games. This is not a lot of time for a beginner player, things are not automatic for you yet and you need time to take in as much as possible. If you can, play longer games eg 30 minutes minimum, really take your time to look at the board, make sure you are not dropping those pieces. The more you take your time, the more you will see and the more you see, the quicker you will see it if that makes sense. The value of 1 or 2 long games in which you have really focused and thought carefully is so much greater than 6 or 7 quick games where everything is a rush. It's also a good idea to look through these games afterwords, try to see where you made mistakes, what you might have done differently now you are looking at it coldly rather than during the heat of battle.
Thanks for the great advice Strangemover As an absolute beginner exploring in chess.com, I needed to hear this.
Thanks again all! <3
