No, you will believe that you have a 1/2 chance of ending up as one or the other. Probability is a mathematical model of belief, not of reality. You can program any number you want in the range [0,1] and that is what you will believe.

Many-worlds is indistinguishable from the case that there is one universe in a definite quantum state, but you don't know what that state is.
