Are you just typing random letters? Terminal commands are basically programs, like word. There's thousands of them, just like there's thousands of programs on windows. And yeah, these programs, or terminal commands can get quirky, but they are also very powerful.
Luckily for you, modern distributions work perfectly fine without ever touching the terminal, so you should be fine if you prefer gui programs.
They've been switching all their software to subscription based, it's coming for windows too, it's less a question of if but rather of when. I'm sure there'll be a "free" edition though, with more ads and whatever else they can think of. Enshittification doesn't stop.
