Yes, boxers come up and pad their records vs lesser competition. In most cases, they don't even hide the fact that's what they were doing. Someone in another thread posted something said by Khabib's dad that equated to the same thing. That they really didn't want to challenge him much before they were 100% sure he was ready. While most guys start to challenge themselves earlier against better competition (even in Europe and Brazil, though I agree not as quickly as is typical in the U.S.), Khabib was still beating up overmatched regional fighters. Would he have taken a loss early on had he taken a route more similar to what most American fighters do? Impossible to say.
See, the problem is you're focusing on the wrong thing. You tell me to "educate myself", but the thing is that I actually realize that's how things work in other places. It's not right or wrong, it's simply how it's done in some cases. The funny thing is that the whole discussion was about putting into context his unbeaten record prior to him coming to the UFC. He fought basically 2 legit fighters. Again, that's not saying he SHOULD have been fighting better guys to develop in the most efficient way. That was up for his handlers and he to decide. What they've done looks like it's worked pretty well. But IF more up and coming fighters took that route (again, I'm not making a judgement on if it's the best way or not, I'm simply pointing out reality), unbeaten records like Khabib's would be more common than they are now. Especially with American fighters, since (as you sort of pointed out) this isn't the typical path they take.
So the problem wasn't my knowledge or lack thereof, it was that your focus seemed to be fixated on defending his pre-UFC record. Which is puzzling, because your defense is "Well fighting more often in a fighters early years but making almost all the fights against sub par competition is normal in these places". That's fine, but it has nothing to do with the fact that I originally simply posted his unbeated record needs to be taken in context of who he fought. It doesn't matter WHY he padded his record that way (again, not judging the career path just stating fact), the reality is that it's a padded record. Obviously he's proven himself to be world class. No question. And not just any halfway decent fighter would go undefeated against the guys he beat pre-UFC. Also not what I'm saying. My point is that OTHER world class fighters would have similar records if they were handled the way he was early in their careers.
Hopefully this makes sense to you.
