Unfortunately, the article is not particularly precise here. The actual statement is that if you're in n < 7 spatial dimensions, then the existence theorem of the paper holds. (I.e. if conditions A, B and C are met, there will be a black hole, more specifically an apparent horizon.)
As far as we know, we are in n=3 spatial dimensions, though. (Yes, string theory claims something else but the results of the paper only hold for n non-compactified spatial dimensions, so they don't apply to string theory.)
