That's impossible to say on an individual level, but it is very likely. If you phrase the question differently, there's a pretty clear answer:
>On average, are two white people more employable than two black people?
Without knowing any further info about the possible candidates - Yes. Looking at education statistics in the US, it becomes clear pretty quickly, that the average white person has a higher education level, than the average black person for example. That's a pretty important factor to look for as an employer. I'm sure statistics on work experience will look similar.
And of course this is quite racist, but as long as different races exist, that really just means taking reality into account. Pretending there are no differences between different population groups is insane and counterproductive.
