No, not a statistical significant difference. If you would pick 100 white people and 100 black people at random and then compare them you would always find a difference whatever property you would choose to study. But if you would repeat the experiment you would get a different result, and after 100 experiments the aggregate would show that there were no difference.
Or imagine this. You are an idiot that believe that long haired people are srtonger than short haired ones. You get 100 buzz cuts and 100 mullets, and lo and behold, the mullets were stronger. But this is sampling error, it was just coincidence that they were stronger, actually, when you cut a group in two and compare them there is almost always a difference, since it is very unlikely that the groups are exactly the same.
