Are the EV principles that are used in photography the same in video production?
Yes.  For things like exposure time, EV, f-stops, video is just the same as still photographs.  You just happen to be taking 24 or more of them per second.

The one difference in actually exposing a frame would be that still photography typically uses a mechanical shutter.  (You can hear it k'thwap when you take a picture on many cameras.)  But video uses an electronic shutter.  This could very slightly effect things like how motion blur looks, or how parts of the image are exposed over the course of the exposure time.  But that 99% doesn't matter, especially if you are just getting up to speed on the basics of things like f-stops.
