Just in case anybody is still confused, I updated the OP :)
These figures are just for South Korea. The Switch launched on December 1st there and had a few localized launch titles for the release. There are still games that have not released there yet, like Splatoon 2 and Zelda BOTW. As you may see with the comments on the article given in the OP, there were some people asking for Zelda BOTW :) Although I'm not sure about Zelda's overall popularity in the region. I guess that's research for another day ^^
