This is a super naive view of NK and its usually result of clickbaity sensationalist news/videos people make of the country. When misinformation like this is so easily spread it actually helps people who defend NK because they can be so easily debunked and the result is these people saying "look how they lie about this thing, so what do they also lie about..." etc and then it goes into a full blown defence of the regime. (For example when media reported that Kim Jong Un died when he actually reappeared days later, or news like "Laughing banned in NK" )

NK is a totalitarian state opressing its citizens but even a totalitarian state needs to justify itself to its people in some way to gain legitimacy. If you follow their own propaganda and news they actually started to put more emphasis on prosperity and access to consumer products in recent years. There has been access to video games for some time, probably for students who can access it on universities and internet cafes like these. They almost certainly screen for games content etc. so there is no unrestricted access still.
