Yeah the analogy isn't perfect, but despite that I think it basically works as a macro representation. Obviously the ball isn't a fundamental particle and we wouldn't have all information about how it ages. But tracking just the ball's position is meant to analogize the fact that we have all information about e.g. a fundamental particle's position.
