And a warm welcome to this imposter syndrome help group, we are always afraid of missing out on some tech. Accept it, everyone is missing out on most of the tech.
When I was studying CS in college, I always wondered why the classes don't teach us about the hot Windows programming thing. All we did were tiny console C programs. I realized that very late, CS classes are meant to let you know about the fundamentals. You probably won't use these skills directly at work, but you will have ideas about how the languages and systems work internally. That pays in the long run.
Just go explore and make mistakes, you will be alright.
