Be careful who you're getting "know your worth" advice from.

Are you in the same bracket of marketing appeal? Are they coming from a position of privilege or already established influence?

Yes, know your marketing worth, but also recognize it's earned and varies per situation.
If your idea of having worth as a content creator is getting paid every time, you're claiming to be in the <1%. Are you? Or are you unintentionally turning down stepping stone/proving ground opportunities?
Knowing your worth also factors into getting management. Do you actually need an agent or are you tacking on extra fees and pricing yourself out of opportunities?
None of this means get taken advantage of. Some of that comes down to gut feeling. Some of it depends on your value of your time in that moment (can vary with life changes). Maybe you've done your quota of sponsorships and don't want to overload your viewers. Lots of factors.
In content creation, continual sponsorships come through proving yourself over and over because it's volatile and highly numbers-driven. It can be exhausting and only a tiny percentage ever make it to ultra mass appeal (viable to any campaign).

Pace yourself and be realistic.
People forget just how many creators there are. Just as marketable creators have a massive amount of choice on what they do, companies with budget have lots of choices on who they spend it on. It's so competitive. Unlikely for most to stand out without SOME "exposure" work.
Even if you do already stand out, there will always be other creators who may stand out more per campaign for various reasons: they have diversified channels to capitalize on (live and vod), stronger social engagement, their content is better edited or more highly produced, etc.
P.S. Many of the creators who talk the GET PAID game are in positions of privilege or having just been "first." Their start is different from most of yours.

Minority creators struggle just to be SEEN. It's not right, but that perspective is missed often in those threads.
Personal example:

I have some usual suspects I turn to as a starting base for sponsored quirky indie game launches because they demonstrably show them well over time. Those names get switched out as others outperform them or provide better marketing value.

That's just business.
What is more marketing value? So many factors, but let's assume all things are equal in target KPIs between a set of potential creators to sponsor. One big determining factor is having more diversified followings, including social and both live + edited vod content.
You've entered into one of the most competitive industries that is accessible to numbers unlike most other lines of work. The baseline and trends change so often.

If being a marketable creator who gets paid is your goal, be aware, agile, and adaptive, and diversify. Earn it.
I'm repeating things because I'm working and randomly want to add on, hahaha.

But one more tidbit: more and more marketers are looking for more creative content outside let's play streams/videos. I'm not saying live in a niche, but having one on top of standard content can help.
Some examples of "more interesting" creative content I've sponsored over a big channel let's play:

- Tips and tricks/in-depth guides
- Speedrun showcase
- Live art creation
- Comedy skits
- Game shows/competitions
- Interview hosting
- Cosplay (jk, still wishing for this)
