Kinda, I use Unity in my day job and I'm setting up my own studio now. I've been making games as a hobby in my free time for more than 10 years :)
Check out global game jam! GGJ is (pre-covid) an in-person jam, I assume after the pandemic it'll be the same. There might also be a few groups for game dev in your city, here in Sheffield we have SHINDIG 😁
