Yes, which was rolled out recently, and when these talk to each other it falls back to SMS, there's Messenger/WhatsApp/or whatever people are using today.
That's not the point I'm disagreeing with though, it's just a reminder that the claim that "most people" own an iPhone is delusional. It's just as ridiculous as someone only hanging out with billionaires claiming "most people fly private jets", and it can be healthy to consider the rest of the world from time to time.
I live in Europe and while iPhones aren't uncommon they don't have the status they (seem to) have in the US and most people use Android.
