Yes, all those cases are true, but it reduces all damage by 10%  on average. Sure, it could, in theory, prevent you from taking any damage on an entire run, but that is astronomically unlikely. Same deal for never preventing any damage at all. As the number of hits you take increases, the percentage of damage reduced by one Hermit's Scarf approaches 10%. Law of large numbers, buddy.
