The distinction is important! The mechanism by which surgical masks prevent you from getting COVID-19 is peer pressure: it's important for people to know this, so they know how to protect themselves. (And there are fitted masks that protect the wearer: there was just a shortage of them, because despite all the warnings we were not prepared for a pandemic.)
The distinction does matter, because by not wearing a mask, instead of indicating that you don't care about your own safety, you're indicating that you don't care about anybody else's.
