If you’re 800 FIDE rated over the board you’re not going to be 800 online. You’ll be way above that. I haven’t played in years but I was beating 1200 rated players online as a total beginner. The ratings are not comparable.
A sub-1000 online rated player is frankly a very poor, total beginner at chess, not an enthusiastic club player.
