Am I playing with/against bought accounts?

So I'm fairly new to this game, haven't really thought too much about pretty much anyone I've played with as I've just been super busy having to google shit I die to read what heroes I'm against do etc. but recently now that I'm 50 hours in have some knowledge I've been left with more time, thus I've started focusing more on what's happening around me.

And boy has it been weird. People with 500+ wins not stacking camps, not pulling, not caring about wavestate, not understanding that maybe if we see nobody on the map going to hit their tower isn't the smartest thing etc. just complete lack of understanding for even the most basic things

Things that you can't really fuck up at unless you're griefing or just so new that you simply don't know that those things exist and it's very clear that these people aren't actually griefing (or they're masking it insanely well and even the idea of actually griefing normal games is wild lmao)

Then I started thinking, am I playing with or against bought accounts? That would actually explain it, it doesn't make sense for someone who's sitting at 300 hours to not know of these things, you'd have to completely lack critical thinking or just be extremely high on something for the entire duration not to pick small things up.

I then googled "dota 2 accounts" and obviously found several sites selling accounts, so I know it exists, I just have no idea how common it is
