I need advice on what type of jobs I should look for

Hi everyone!

I could also use some straight-forward critic on my videos. I know I have plenty of room for improvement, I just need to better spot it.
Should I expect an over-saturated market where one has to start working for free for a long time?

I’ll tell you a bit about me so you’ll know what is my background.
I started making YouTube videos about 3 months ago.
Although I did not finish University, I did study for 2 years in the Graphic Design program (50%). I worked in the PhotoLab developing and printing photographs at the University’s newspaper.
Years later I obtained a diploma in 3D Animation & Multimedia. Ever since I was a small kid I liked creating different things. Like figurines with plasticine, clay, and bar soaps, drawing and some painting, and even cooking.
I am enjoying very much making videos because I can get to use many disciplines in one place. And, at least while I do it as a hobby, I get to choose “what goes, and what won’t”, so that’s nice too.
But now I’d like to turn this hobby into something profitable so I could stop doing the “non-creative” work I normally do.

I am entertaining the idea/notion that if I polish my video editing skills I could aspire to a paying job. How wrong am I?

I would like to put forward these 2 different videos. Hopefully, you can see enough potential.
1. Play Astroneer in Linux – A Follow Up (00:05:46) https://youtu.be/Pfy467ADlio
As for the music chosen, keep in mind that the game soundtrack style is Ambient music too. So I am going along with that.
2. Deleting Multiple Clips at Once with Shotcut (00:03:45) https://youtu.be/Vc6bGgIui_c

I am using all Open Source software: Shotcut, Gimp, Inkscape, Blender 3D, Audacity, OBS, etc

Thank you in advance for your valuable time and advice.
