The difference in age demographics isn't nearly enough to account for the differences in outcomes, unless you believe the proportion of people in Italy >70 years old is 5-10x that of South Korea. (Spoiler alert: it's not). The issue has to do with preparedness and healthcare capacity. South Korea has 3x the number of hospital beds per capita than Italy.
