What endgame fundamentals I need to know?

1200 lichess. I know how to mate with a queen, with a rook, with 2 rooks. I can make a very basic engage plan (attack on left v right depending on how many pawns they have, counting the squares).

I know I need to learn opposition, lone pawn v king endgame, Lucena position, Philidor position

Is that enough for now? Clearly at some point I'll need more, but if I learn the above and drill it, is that enough to pass 1500 lichess?
