How can Many Worlds be reconciled with unequal probabilities

[Sherwood Botsford]

If I understand the many worlds QM interpretation correctly, for every quantum event the universe divides.

However not all quantum events have a 50/50 probability. How does the many worlds interpretation deal with quantum events that have,say a 1/3 2/3 probability split?

I have been told that it is the probability that you end up in a certain branch. But that would suggest 'you' don't end up in a different branch. I find it puzzling.

That's essentially the problem of the origin of Born rule in MWI, which is an unsolved problem.
