Surely the testing is a huge factor. Test more people you'll find more people infected, so the fatality rate will get smaller. If you're like the US and test very few you get the huge fatality rates we saw in Washington.

It also allows much better isolation, understanding of the progression of the disease, stopping that progression and so-forth. So sure, the Korea rates don't prove Korea has magic dust that cures the problem but shows the Korean model is effective.
