HI @canopymaker !
Congrats! That is where I started back in 2020 
While you might not be at a university, you do have resources available to you.
There are tons of discord communities, slack groups, etc that have tons of developers of all stages all learning and growing together. I would suggest starting with the freeCodeCamp forum and discord and go from there.
There is a lot of context missing from that youtuber story. When did they get their job? Did they get it during the height of hiring tons of devs during the pandemic? How much programming experience did they have prior? Did they have skills in other areas like math or engineering that made the transition to programming smoother? Did they already have a preexisting network of tech friends they could tap into to get leads for a job?
The reason why I ask all of those questions is because context does matter. Lots of people hear these stories of those getting jobs quickly and think it can be easily duplicated. But for most people it won’t be.
Some people get jobs very quickly because they are ridiculously good at networking and had opportunities presented to them. Others just happen to be at the right time right place. Others were already connected in the tech field and had friends help them get the job.
A most realistic timeline will be close to 2 years of learning, building projects and networking before you get that first job.
As someone who is self taught and has worked in multiple dev roles at this point, I can tell you having time to build a good foundation in the fundamentals and building projects on your own is key to being successful on your first job. So take your time with learning and growing because it will be a huge help 
I think you can get accountability from being involved with communities and learning in public. A lot of people will participate in 100 days of code and post about it in discord communities or twitter to help keep them accountable. Others will publicly post about a project they will build this year to force them go through with their plan.
But the main thing is to just stay plugged into a community like fcc. Because things will get tough and you will have times where you wont’ want to code. That is normal and happens to all of us. But if you are plugged into a good community you can share those thoughts of doubt and the community will help you through it. 
Going through the self taught journey is not easy but 100% doable when you are plugged into a good community and you take the time to engage and learn from the community. That is where you will learn tips for learning in general, tips for building projects on your own and tips for the job hunt.
Hope that helps
