How come so many lvl 10s? 10%

Hadn't played this game in a while. At new years i decided i'll pick it up again and hit level 10 since cs2 came out. I was a proud lvl 5 boyo since last i played i deranked a lot, but was also previous level 10.
Anyway, 4 weeks into my objective and i went from5 to 10. Super easy.
In fact to easy, and then i also learn that theres 10% of players on lvl 10.
>_>
Whats going on here? Excuse me if its not the obvious.
WhAT i had noticed on my road to 10 was many premades of 2.3k elos with lvl 3 or 5. Like LOTS of these type of premades. Most of them 2.3k elos being really bad or max lvl 8's in actuality.

Is this why ? Or something else?

I remember in 2019 when i got to lvl 10 at 2003 elo and there were 18k accounts above that, not 70k as there is now.
Kinda feels like 10 lost its prestige, the new 10 or 1% is 2.5k elo.
