The some stereotypes are based in reality comment was meant to indicate that the fact is there are real differences between the average behaviors of different groups of people. So when shown clear evidence that groups behave differently, it isn't racist to point out that groups behave differently. It would be great if we could have a discussion about real differences in how groups of people act without being called racist.
I could definitely believe that black people are less likely to tip (or avoid paying altogether), as black people are poorer (on average). Black people are also much more likely to commit violent crime (on average). Note that cab drivers are likely to not be white (on average), at least in my experience. I did some research and it appears to be common for cab drivers to avoid picking up black passengers - this is pretty strong evidence that cab drivers have had negative experiences with black passengers.
It is racist for cab drivers to avoid picking up black passengers, but we shouldn't pretend that they don't have a reason for it.
