It depends how much you've played. As a benchmark, Carlsen's FIDE rating was 2100+ at 11 years old. If you had a FIDE rating of 1800 then you'd be in the top 25% of FIDE rated 11 year olds. Online ratings are difficult to have confidence in. In your case, we can see that you've lost your last 2 matches to 500 rated players. Which would be almost impossible for a 1800 rated player.
My lichess elo is 1800 and I just wanted to know if that's good or not.
