as much as i like chess legends, i also hate it

it's so difficult. i can't win, i keep losing. no matter how much i grind, i keep losing and then i lose so many points. i don't know how others get to 1000 points, my peak is at somewhere in the low 500s, i keep losing and now i'm hard stuck again at around 250-350 range.

any tips on how to break past 1000 points like everyone else is?
