I mean, of course he could learn it. But it's wayyyy better if you learn it young. Easier to learn instruments when you're young, and a lot more time left in life to master it.
I have no idea who he is, but it's totally possible he might have played at one point. It's a stereotype that asians are good at piano etc cause their parents make them play XD
And it's kinda true to a large extent. There are so many asian pianists though! they're amazing XD
