...or rather learning is living (with or without the fully) would be the parallel with the original quote. They are not saying "to live is to learn" which is already a known aphorism, but to learn is to live.

To me the quote as given SOUNDS smoother than "to learn is to live fully" which sounds more formal and stilted. But I agree that the infinitive plus participle does lack a certain grammatical symmetry.
