This is one of those “unask that question grasshopper!” situations.
There is according to Everett, just one world, consisting of the wave function.
As macroscopic beings we experience a projection of that wave function onto a lower dimensional space. One can think of one projection as one ‘world’ but really there is just one world. You have to read the whole thing unfortunately to really see it.
As quantum measurements occur the projections ‘split’. This creates the illusion of indeterminacy because we only see part of the world.
