Computer Science may be intimidating but like any other field of study, you don't have to learn it all at once.
In any line of questioning, you can keep asking "Why?" Eventually, you just stop when you think you've learned enough. For example, you can legitimately claim you know how a car works (you put gas in, turn a key, etc) even if you're hopeless as a mechanic. You've got a different acceptable layer of abstraction than a mechanic claiming too that she knows how an a car woks. The inner-workings of a car engine may just be an abstract idea that you only broadly understand (something about spark plugs). The point: You can start learning really cool tech without having to shift your acceptable layer of abstraction too much. It'll be fun.
In order to understand basic computer programming, you will need to understand some of the components in your computer. If you understand the basic shape of the environment, the behavior of programming languages will have better context. You won't need to understand exactly how a processor works, but you'll need to know roughly how it fits into the picture so you can solve some common problems.
