He was also a Nazi, and Einstein hated the implications of the the equation and spent most of the rest of his life trying to disprove it, only to fail utterly.
Heisenberg's theory is very basic, but it proves that if the position is determined the momentum cannot be known. It is why electrons don't spiral into the nucleus. The theory explains much of the known universe.
The synthesis of all of this is that nothing can be known with certainty. God indeed does roll the dice and even he has to wait to see what the outcome is.
God is outside of time. The dice have already rolled in my view.
