To add to what escada said, there’s actually no guarantee that the language used in the “name” tags in OSM (which is what you highlighted in https://ibb.co/xfh6MnL) would necessarily match the most-used language in any particular country. Many countries have people speaking different languages. To take just one example, my own country (the UK) has people speaking many languages, with about 4 or 5 having some sort of “official” status, and when I create a map for it I split the country into 4 “language areas” that determine what name to show. That’s impractical to do across the world, and so the “standard” map tiles you see at OpenStreetMap.org will show just “what’s in the name tag” - which tends to be what the people speak locally at this moment in time. As https://wiki.osmfoundation.org/w/images/d/d8/DisputedTerritoriesInformation.pdf says:
However, as that PDF also says, if you’re creating a map or an app you’re perfectly free to use whatever name you like, and many people do.
