How easy is it for High School freshmen to get internships?

I’m really interested in Programming. I learned JavaScript in 7th & Java & Phython this year and made a couple websites and bots and stuff, but I really feel like I haven’t mastered it, even after reading tons of books and udemy courses.

So, I want to intern at some IT company for a few weeks. The problem is that most of these companies have an age or class restriction(to Junior or Senior year).

Do any of you have any experience and/or tips relating to joining the internship programs? If it’s impossible for me now, what steps can I take now to help me get a good one(I really want Google) during my Junior or Senior years?
