In my experience, 'data scientist' has become a very loose term, especially in the not terribly sophisticated corporate world. Typically, 'data science' isn't even very scientific, but a useful set of heuristics to get good model outcomes on data. Rarely is actual 'statistics' being done to get scientifically rigours results. People employed as 'data scientists' often come from comp sci/physics/eng/econ etc. They might be great at fitting models that also have great out of sample prediction performance, but they may have never heard of maximum likelihood, or know when to use a Wilcoxon rank sum test.
