I've never seen this venn diagram before--thanks for bringing it up. I find that, as an academic (pursuing a Ph.D. in astrophysics) that plenty of traditional researchers are able to hack together code (many haven't ever taken a formal programming course; http://arxiv.org/abs/1507.03989) but many also misuse or can't interpret statistics (from personal experience). That puts us in the danger zone!
I think the key is to find the mathematics and statistics interesting because you want the [data] science to be meaningful. If that's a driving force, then you can learn math and statistics on your own (like the author did). Otherwise, yes--you will find yourself in the danger zone.
