That sounds unlikely because empirically Certain Things Happen and Other Things Don't, and you need to be able to explain why. With examples.
MWI honestly sounds like the philosophical equivalent of No True Scotsman with added Meatloaf - no one is really sure what it means in detail, but they're somehow sure it doesn't mean that.
MWI explains that "Certain Things Happen and Other Things Don't" is an illusion - everything that can happen, given the quantum probabilities, does happen. There is an infinity of branching outcomes. The only reason you perceive that Certain Things Happen is because, despite there being infinite paths from the root of the tree to a node, there is exactly one path from any node (where you are) to the root of the tree. So you look back and each moment appears to have followed from the previous, because it did. But the moments you experienced aren't the only ones that proceeded from the moments prior.
I think a typical criticism of that is that Many Worlds replaces the mystery of wave function collapse with the mystery of why we are on this branch rather than one of the many copies of us on other branches.
