"You may remember that this exogeneity assumption is somewhere in between no correlation and independence." - What is meant by this? And thank you for the videos.

It is right in the middle between both. Making the assumption of independence would be too strong and it suffices to only have conditional mean independence. No correlation is even weaker than conditional mean independence, so the CMI assumption is a good middle point. Independence-->Conditional Mean Independence--> No correlation. The other war around does not work.

What do you mean by OLS Sir??

OLS means Ordinary Least Squares (Estimation) which is a method to derive an estimator for the parameters of a regression model. The idea is to find regressions weights (beta-values), so that the squared difference between our estimated values and the true values becomes minimal.
