Comparing Quantum Mechanics with General Relativity in a direct manner is like comparing apples with apple trees...
Actually the one is nested into the other. That's what makes this equation work out in the end.
Or as Hermann Haken put it "Microscopic chaos creates makroscopic order." (Synergetics) - this is when a deterministic system, such as proposed in GR, is created by a subset system of probabilism, as proposed in QM.
