“Many worlds” here is shorthand for “every time some event happens that has more than one possible outcome, for every possible outcome, there is (or comes into being) a world in which that was the outcome.”
As far as the truth or falsity of Many Worlds mattering to us—I don’t think it can matter, if you maximize expected utility (over the many worlds).

That is not what Many Wolds says. It is only about quantum outcomes, not “possible” outcomes.
