The main thing is that 1000 is not a beginner rating.
If someone learned chess for the first time, meaning, if someone didn't know how the pieces moved yesterday, then their rating would probably be below zero if we're being honest... but of course it will quickly go up.
With no other instruction, and a few months of casual playing (maybe 100 games total) they'd probably be doing quite well to be rated around 500... at least if they knew the values of the pieces (queen, rook, bishop, knight, pawn = 9, 5, 3, 3, 1) and maybe a basic checkmate (like two rooks vs king).
1000 is low, sure, but at the same time it combines some experience and some knowledge. For example the opening principles and basic tactical patterns (forks, pins, discoveries, and removing the defender). Many people also casually watch youtube videos by masters, which isn't very instructional, but it's better than nothing.

So for example in your most recent game against @eversnaxolotl you play 3...f6 to support the pawn push e5, but moving the f pawn in the opening is something all beginners are told not to do. Mostly because it weakens the king's position, but also because it makes it harder to develop the kingside knight.
On move 12, your opponent played 12.Nxf6 which was a check and a "discovered" attack on your bishop (moving the knight uncovered the queen's attack). If I were new I'd certainly be amazed by white's idea, but in truth this is a common and basic tactical motif.
I've only played like 6 games and I'm already very clearly seeing this - despite being completely new and at the default 1000 rating, the people I play against are just so much better. What's the reason for this? Are people intentionally keeping their rating down so they can smack Newbies around? It's really frustrating to just start out and already get beaten easily by almost everyone.
