Also, when you are in the process of learning a new language it is perfectly ok if you don't know what's going on. You don't have to understand everything, and you don't have to know what tense is what, or anything.

Learning language is something that humans do, sort of like digesting food. It doesn't help to worry about it so much.

Think of little kids learning a first language. There is quite a lot that they don't understand, sometimes it is adorable, sometimes funny, sometimes frustrating.

Just keep up your exposure to the language and you'll get better.
