It’s unlikely that there is consensus on where the line that separates them is, but to me influencers are showing their overall lifestyle (day in the life, vlogging, sharing their meals, routines, that kind of thing) and content creators are primarily generating something else that is not necessarily dependent on their lifestyle. I see it as educational content, creative content (arts, DIY, movie commentary, etc) news… I know content creators often expand into what I described as “influencer content”, but that is often not their primary way of getting followers or focus of their attention, so I still think they are content creators.
