So 20 percent of players have a rating below 1000 according to what I saw
Given that 1500 is 50 percent of players...1500 there is equivalent to 800 here
It is 11.3% actually.
What is 11.3% ?
The percentage of players that are rated below 1000 in LiChess.
Your 20% is wrong.
I think I was referring to Chess.com.
But then time controls have different percentiles too if memory serves.
Elites who claim that a person who has played for 20 years is a beginner can go sit on their thumbs.

Huh? <1400 doesn't exist!
This is true for standard time controls. Rapid and Blitz ratings are still on the 1000 base.
