The training time and taking it seriously is the key thing.
It goes the other way as well, Ngannou had an amateur bout vs Carlos Takam and was sparring Joyce last year, I think he spent the best part of 2 years preparing for a boxing match not 12 weeks.
Mcgregor just had one camp and we saw how that went, he'd have done better (still wouldn't have won) if he dedicated more time to it like Ngannou.
