Einstein was very disturbed about what he called, "spooky action at a distance", the idea that the very core of science would be probabilistically determined was to him the equivalent of, "There is stuff in there we just don't know about."

Right. Einstein had trouble accepting that the universe was not deterministic. Probably because there were vestiges of his religion that stuck with him. He eventually came around, though.

But that doesn't mean we don't understand a lot of it. Einstein even put dark energy into his equations long before we recognized that it existed. He called it the "cosmological constant". He later decided it was a mistake and took it out. So it was the case of him thinking he made a mistake and it turning out he was wrong about that...

The reason he put the cosmological constant in is that he realized that gravitation would cause the universe to collapse, given enough time. And, like with his problem with the probabilistic nature of quantum mechanics, he didn't want to believe that the universe was not eternal. So he hypothesized a repulsive force that would keep that from happening. But that didn't make a lot of sense, so he later removed it. Turns out, there actually is such a force and it has a value that is very close to his cosmological constant.
