I don't think those numbers can only be reached with helpers.

How much effort camera/editing is really depends on the genre. E.g. for gaming channels, camera work basically doesn't exist, so it's "just" editing (which again highly depends on the style). At the lower level of "professional YouTuber", having to pay someone else vs doing it yourself would also make quite a difference for making the financials work out or not. Actually, I'd guess in gaming the most common external help would be a chat moderator for live streams.
