A standard CS program will cover statistics (incl. calculus-based stats e.g. MLEs), and graphics is a very common and popular elective (e.g. covering OpenGL). I learned all of this stuff (sans shaders) in undergrad, and I went to a shitty state college. So from my perspective an entry level programmer should at least have a passing familiarity with these topics.

Does your experience truly say that the average SWE is so ignorant? If so, why do you think that is?
