It's the same thing as being confused when you are trying to learn how the paper money is printed and the whole economy itself.
Don't worry about it too much, bud. This forum is open for everyone trying to learn or just trying to have a discussion.
I, myself, am just interested in blockchain programming but that's it. I do not know a lot about the technical stuffs in Bitcoin, but it does not worry me same goes on how I learn programming in general. It would be beneficial to learn a lot, but you don't need to nor should feel bad about it.
