I'll see your anecdote and raise you one ;-). I never used to floss, and would regularly have cavities to deal with (pretty much every visit to the dentist). When I started flossing religiously that ceased. I've had one filling (and that for a tooth cracked when I accidentally bit down on something hard) in the last decade. For me, there's a pretty clear benefit to flossing. I imagine there's a lot of variation in its usefulness, depending on things like diet, mouth shape & size, what kinds of bacteria you host, etc.
