"Wild" seems like a stretch. I feel like it shouldn't be too hard to believe that some people drop their phones occasionally, and it's a reasonable concern when it's likely to be with you everywhere you go.
Edit: sibling comment is correct, sketchy pockets of athletic shorts are a major offender. Actually it bothers me way more when my car keys fall out of those.
I never used a case until I got a Galaxy S9; that phone was like a greased eel. Went from dropping my phone zero times in 8 years to 5 times in one week.
