Depends on how long the video has been out and whether it crosses over from fandom to GP recognition.
When a video first comes out, it's usually fans watching it, so you usually get a higher ratio of likes to views. Maybe 1M likes for every 10M views.
Then as time goes on, more and more randos start watching the MVs especially if the video goes viral and hits mainstream non KPop listeners, nonfans who naturally wont be as likely to click "like". So the ratio increases, even for non ad supported MVs.
Everyone knows that BTS dont use ads. Yet some MVs like Suga's Haegum are more fandom centric and have a 1 to 13 ratio of likes to views, while others like Seven by JK has kinda blown up with non Armies/non Kpoppies and has a 1 to 20+ ratio of likes to views.
So with Jihyo, her relatively high amount of likes probably means that JYP isnt using any ads, but also that she hasnt broken through to non Onces yet with the song.
At least this is my theory.
