I think that one doesn't come from being fancy, but from machine learning being the terminologically-uncomfortable collision between statics mathematicians and computer scientists, who previously had essentially no cross-talk with each other. There's a number of similar places where ML uses statistics terms rather than ones you'd expect from a computer science (as a branch of mathematics) heritage.
