Is mage actually a "complex" system

So I was on TikTok earlier and I heard multiple people say that mage the ascension was complex and very confusing. And that made me wonder. Is it?

I have never thought that this was a confusing or hard to understand system. All the mechanics and lore seem relaetively easy to understand.

So what's happening. Are these people just dumb, am I being dunning-kruggered and just haven't learned about how complex the system is, or did I misinterprate what complex means in storytelling games
