Because of my unstructured learning and random hobby type direction it took me a couple years to get proficient, but eventually I knew more about systems admin than people who'd been doing it professionally for years. I got hired for peanuts by a startup, and networked through User Groups to a better job that paid more.
My career's been nearly 20 years with no higher education or any other skillset whatsoever, bad at concentration and memorization, no bootcamps or teachers or mentors. I'm not a genius. If I can do it, you can do it.
An unlimited amount of free information and learning is out there on the internet. Go and get it, learn it, practice it. Network and find someone who wants to pay you chump change and build that resume.
Also remember there are a lot of roles today in tech. Many don't require a ton of technical chops. Figure out what they are and what they entail, and target your learning towards one. Even lower end roles pay better than most other jobs, and you can always pivot to another role later once you have some work on your resume.
