I think it muddies the definition to apply a "goal" relative to their income to either of them. If someone makes content, they are a content creator, without question. Some want to make a living doing it, some just do it because they want to. Both are content creators, regardless of the income. Influencer/CC is a rectangle/square categorization. Influencers are akin to advertisers.

I completely disagree that a content creator who takes sponsors from other companies, are NOT influencers. If they are acting as an advertiser, then they are influncers, they are still content creators however. If a content creator is just making content and selling their own wares, they are effectively advertising themselves; which is totally fine. If I am engaging with their content, I am already interested in their work.
