Cheaters vs. Skill issue ❓

Everybody just talking about cheaters, but... it is that big problem? Or is it mostly only skill issue, bad gear, bad map knowledge, no sounds etc.?

I have only like 130 hrs. So in my eyes I get like 1 cheater in 20 games.
But Im watching a lot of videos/streams and when I see what ppl in top ranks know about positions, peeks, angles, jump spots etc. sooo... their dead enemies probably think they are cheating.

I dont wanna say there are no cheaters right now, but is it the problem with them that big?

Is it there more ruining stuff?
Like "squad fill" people without mics, running solo without team, looting&diyng instantly by AI/bosses etc.
Or game mechanics that allowing purple/gold geared squad running easy mode?

Everybody should start looking how to improve, why they die, what they did bad and stop blaming all on cheaters.
Blaming doesnt fix your KDA or stash value, only make you look like crying kidos.
