Might depend on what exactly one considers a point of interest, but looking at some common keys:

- http://taginfo.openstreetmap.org/keys/tourism

we get around 20 million features that could be potential landmarks or points of interest.
Just counting points that have names, we get around 12.9 million features.

By counting features in maps.me maps, I found around 11.2 million POIs with names, quite close to your estimate.
