Edit. Also, I was wondering why there was no French Guyana, but being part of France means it's not a separate country. However, in that case France should share a border with Brazil. I wonder what other such quirks are in this map.
Also, there's a new land border between Canada and Denmark, and not depicted on this map, since the border did not formally come into existence until 2022. https://en.wikipedia.org/wiki/Hans_Island#Resolution

I think the map in the main article and the graph in the game ignore exclaves and other weird topological parts of countries, but they may be ignoring or counting them in different ways.
Anecdote time: A few years ago we made a math exposition and we wanted to show something about the Four Color Theorem. We were advice to not use a real map, because each country has their own claims and somebody somewhere may complain.
Yes that confused me too. If they included Morocco, then France should border Brazil and Suriname.
I just did my first second-hand inference and it was satisfying. Turkey borders Bulgaria and Greece, don't know which is which, but those two both border North Macedonia, which was a correct guess.
