Well, it's not 2008 anymore.
What you cannot expect is that you can make enough in ad revenue to pay you what your time is actually worth.
Unless the value is in doing the work, not being paid for it.
If you have good content, you will have page views and subscribers.
You will also have haters, too. People who only exist to come be trolls, and they will pick on you mercilessly (or attempt to melt your brain with their imbecility. Remember that we have a world fueled by "offense." They will hit the Report button just out of spiite. Enough Reports and the algorithm will give you "strikes." Three of those will shut you down.
Serious meanies will file "copyright" complaints against your content, too. So, know the rules for excerpting material, and "fair use."
It's a really good idea to go ahead and get good editing software first. Then, plan out a watermark/trademark. (Go ahead and file the thing as a ™, just print it out, along with a page title, and send it to the Copyright & Patent Office, it's around $20.)
Not a horrible idea to sketch out how you want a video to "look" before you roll any tape. Shoot some text video first, and look at it closely. Be sure it look like how you want it to look. Make sure there are no advertising signs, neighbors who garden nekkid, or the like in the background. Watch the test video on a small phone and on a big screen.
One of the harder bits is to remember to speak to the camera as if it were a person, it is the window your viewer will see you through.
