He's saying uneducated in the context of technology (pretty much in those exact words). This means they don't know that what they are seeing in WhatsApp is fake and/or taken out of context. They don't know about common scams, or which sources are trustworthy/reputable. They don't know where to look to find out this information, either. Sure there are plenty of people like that everywhere you look, but the proportion of them in urban areas is much lower and as such the probability of them finding each other and banding together for acts like this are much lower too.
