Jazz is not that difficult (on the theory side), because most of what players do is to decide on the fly what sounds good or not. All the complex analysis of scales is just something that is introduced afterwards to try to understand what is going on, not something you need to learn. The only concepts that I believe you need to master to play jazz is basic chords sequences (II/V/I style) and voice leading. Everything else follows from that.
