Jhin is about as much of an ADC as Mordekaiser was.
If you don't snowball lane, and you're still in game after 35+ minutes and you're playing against an actual ADC with sustained damage then you will lose. Even if your team was winning hard. At the end of the day, you've put your team up against a time bomb - not because the Enemy team has a hypercarry ADC, but that they have an ADC at all.
TL;DR - Don't pick Jhin as your team's Primary AD Carry and if you do, make sure the match doesn't go past mid-game.
I don't think I've seen an Ally or Enemy Team with a Jhin as their Primary AD Carry win when the game has lasted over 30 minutes.
