Just to put things in perspective, the first non-trial class I ever took in MMA I did a Jiu Jitsu class (or perhaps it was wrestling). I was already an adult, 19-20 years old, I wrestled with someone who was 13 years old and much smaller than me. He totally threw me around. The difference in physical between a 19 year old and a normal 13 year old is probably larger than an NBA athlete vs a 5'10, 180 pound athlete. Again, he was in middle school and I was in college - I was slim back then, but I'm still very much a normal sized person, roughly a bit larger in frame than Conor McGregor (who is probably 180 pounds when he's not dieting).
Also, the first time I sparred I couldn't land a hit on the guy I was sparring with. And in turn, I have sparred with many people, including those who have some training who can't land a hit on me. And I still can't land hits on other guys. Someone who has never threw a punch before will have a very hard time getting a good hit - wailing punches are not effective even with a good size difference, and is more likely going to lead to a broken hand for Zion than a knock out punch.
Someone who is trained vs someone who is untrained is like a guy with a gun going against a caveman. It really feels like one guy is just using primitive weapons. Not everyone who trains is a good fighter though, but McGregor is a professional, and a top one at that.

He definitely could knock someone out that size. He has legitimate knockout power, he isn't just knocking guys out because they're small.
Chin and liver don't correlate that well with size in terms of damage that can be taken. If a legitimately small man like Manny Pacqiao gave someone like Kawhi Leonard a hook to the jaw or the liver, Leonard is going down easy.
