Yup - this is exactly it. I'm entirely certain that there are people out there who have had their financial lives saved from utter ruin via vacation insurance - but I'm also certain (because I've witnessed it myself) that far far more people who think they should be covered wind up in deep shit because their hospitalization came from an accident, or as the result of a crime, or some other edge case that happens to be excluded by the travel insurance policy (and make no mistake, these exclusions are carefully crafted to cover as many potential cases as humanly possible while still sounds decent on paper).
