Sure. I pay for YouTube Premium (which I understand gives content creators a comparatively higher rate for my view) and I still have to deal with sponsorships.
This also goes for channels with well over 1M subscribers. I honestly have a hard time believing they're struggling to make a living (but I haven't seen the numbers).
Worst of all, the sponsorships tend to be for some scammy VPN or gacha, even when it comes to creators who otherwise create high-quality content.
