In my opinion (see also Dr Gabor Maté), addictions (which, I also think, can be about petty much anything) are very much mostly attempts to escape pain, when better alternatives do not seem available to a person.
So, yeah, video game addiction can be a thing, and certain game designs exacerbate that (similar to what might fuel gambling addictions and such).
But all of this perspective only distracts from whatever is causing the people/kids pain, makes them seek out games in an addicted fashion in the first place.
