I'm not quite at the point where I can appreciate how useful this is, because I don't really understand concurrency itself. What is a good resource from which to learn about concurrency, and especially Elixir/Erlang's approach to it?

These days there is such an explostion of languages, frameworks, techniques etc it must be scary for a beginner. Given that, i'd advise to go by the safe (average) path.
Well you see where this is going. I think it's important to learn about Threads, Mutexes, Condition Variables, and why sharing isn't caring, but I don't think those lessons necessarily need to come before learning about the Actor model.
Most devs go from OO to FP because of dominance of OO in industry (with knock-on effects on pedagogy) from sometime around the late-1980s/early-1990s until recently. Shortly before that, the same would be true of procedural to either OO or FP. And probably at one point the same would have been true of unstructured imperative to procedural.
But that doesn't mean that concurrency in popular OO languages of today is easier than concurrency in Erlang/Elixir (which may be examples of functional-ish languages, which I assume is the relevance of your OO to FP statement), nor does it mean that concurrency in formerly popular procedural languages is easier than in any particular OO language, or that concurrency in unstructured imperative languages is easier than in any particular procedural language.
