Agreed, I'm not a huge fan of junior/senior. What we should be talking about is inexpert/expert, which doesn't always map 1:1 with how long you've been working, or practicing. Though obviously, the longer, the more likely you learned and became more knowledgeable. But some people spend 10 years doing the same thing over and over, and that's not broadening and deepening their skills the slightest.

So in my opinion, there is two type of unreadable code, there is the code that's just plain bad, convoluted, overly complicated, like a Rube Goldberg machine. That one is often written by inexpert programmers, sometimes they are juniors, and sometimes they're senior as well. And then there is code that you personally can't read, but which is great code, simple, coherent, to the point, etc. You just haven't learned the vocabulary and grammar to understand it.
