All of your examples count as random events with a collapse postulate, but not with many worlds, and hidden-variables have been formulated both ways.
Based on your past comments, I assume you already know that. Still, since your examples don’t suffice to distinguish interpretations of QM, they also don’t suffice to distinguish a universe with randomness from one without. Or are you just pointing out that we should assign higher probability to randomness than we would have if we hadn’t observed anything that looked like collapse?
