I've been to a developing country where I suspect split between play store and bluetooth APK sharing is about 50/50. Most phones have APK sharing application installed at the point of purchase and some people aren't even signed-in on the Play store, despite using the internet and WhatsApp.
Xender is more popular than Play store near where I live

As commonly? Outside of China, not really a thing. But widely used, and complemented even more strongly with installation of APKs? Yes.
Any source for this? I wasn't aware that third party stores are used by the general population as commonly as the play store anywhere.
