Supposing that every "result" represented a person who knows what you're talking about, that's still less than 0.1% of the English-speaking world. That would suggest that it's a bubble.
(on the one hand, of course most people don't create web pages, so perhaps this heuristic undercounts how many people would know. on the other hand, one person who knows creates many many web pages, and of course instagram people are disproportionately likely to have web presence, so this heuristic overcounts how many people would know. or perhaps your whole comment is silly. I don't know!)
