This is a pretty substantial achievement, if you look at an estimated percentile breakdown: https://www.reddit.com/r/chess/comments/54c1nv/player_rating....

FWIW, I’ve found that on Lichess I’m rated at least 100 points higher than what I would be on Chess.com (the most popular chess site), and maybe 150 points higher than what I’m rated by the US chess federation, which mainly rates live, not online, games.

A player with a rating of 2000 by the US federation would be called an “expert”, just below the 2200 rating that earns you the title of “master”.

Elo (it's a name, not an abbreviation) refers to a certain calculation method of rating. Lichess uses a glicko2 rating system.

You can't really compare ratings from across websites or groups like FIDE since the pools are so different.

200 points in the 2000 range is reasonably significant and something to be proud of.

As a wild guess, amateurs who only generally know the pieces and play casual games infrequently are likely to be less than 1000 ELO, so it's a bit of an achievement to be in the 1800+ range.
