Not an expert, but there are indeed theories that try to do away with these apparent probabilities and reinstate determinism by moving the unfulfilled probability counterparts to the visible collapsed ones into parallel universes. The wavefunction collapse is just an illusion in those theories. It's closer to philosophy than science, even though it's based on actual equations. As it likely cannot be proven, it mostly makes for some interesting science-inspired fiction books. I think people like Brian Greene wrote about this, but I haven't read these books in years so I'm not sure.
