How to prioritize developer development?

Question

IT education

Okay, there is already a question on the toaster with exactly the same name, but my situation is slightly different. I'm 21 and I recently got a job as a java junior in a banking software development company. Frankly, this is not what I expected (and not what they asked me at the interview, Spring / hibernate / REST and all that stuff). They use java 8 (which is good), but the project on which I was now "hung" uses very ancient technology, as for me, the last articles on it in Google date back to 2010. (I will not say which one, suddenly my colleagues are sitting here who recognize me). And after I retire from there in 1.5 - 2 years, I don’t think that I will be a hell of a sought-after specialist.
Therefore, the decision came by itself. Self-development after work. I love my profession and especially love writing code. But I come home somewhere at 19:30 + half an hour for dinner. As a result, I have 4 free hours before I go to bed. I don't masturbate with Java and I'm well aware that it's just a tool in the hands of a developer, so I don't want to build a career around "technology developed by a company that I'm not an employee of".
I like the potential of ML. I started doing it in my free time, learning python and pulling up matan. I like algorithms and started reading Cormen while implementing them in Java and python. I like to solve problems on leetcode, I like the functional approach in hasskell and I want to learn it by implementing some kind of pet project on it, I like the DevOps methodology, I like fucking English, I like the Yandex ShAD and I would like to go there. However, if you look from the side, I just sit on several bottles at once. Fak. I can't properly prioritize and it turns out that I jump from one topic to another without thoroughly finishing the previous one.
I must have some kind of mental disorder or something like that. In any case, if you know the solution to my situation, or at least advice for it, you would be great to help me.
When I spoke out, it even became a little easier)

Have fun! There are quite a few companies still using Java 1.4 and EJB 2.0.
Cobol programmers look at you with incomprehension. Read.
Breakthrough of time!
What you need is not priorities, but self-discipline. Being interested in many things and constantly changing the sphere of interests is not bad, on the contrary. But throwing something halfway is not worth it.
Work for 3 years at your current place, get the status of middle, and look at the situation again, through the eyes of a more experienced specialist.
