You started on the wrong foot. Learning from someone who cannot explain his own code is not the right context to learn any tech.

Redux is a modern implementation of CQRS/Event sourcing, a design pattern that existed before you even started coding. Many developers, in different languages, learned it and used it (if you want to implement an undo stack for instance, there is not a lot of other solutions around). Trust yourself and your intelligence. Our devs learn it in about 3h with our training program and get a return on investment in about a week.

MobX is nice and if it fits you, go for it. If you are a hands-on kind of guy, you may discover the limits of MobX by using it, and from the trenches finally understand why Redux, and why does it need 3 objects (a store, a reducer, an action).
