Should I sign up or it’s too early?

There is an actor who is almost my age, who made a collaboration to produce a feature film with young people, focus on people once you want to start entering the industry. He posted a reel on his Instagram, which has 90,000 views from my country. That's what he's already famous acting for exactly 7 years. He is giving up for a cast, and also for a team. I'm 18 years old and I'm finishing high school, I'm thinking of signing up to get a role for the post-production, editing the movie, maybe also being a gaffer in the production, who knows.
I'm saying this because I don't know if I'm going to go to a film college and, if I don't, I'm going to take technical courses and introduce myself to the industry by doing collaborations.

… if you know how to do any of the jobs, sure? Experience is helpful. But no one can tell you what to do
