The best thing is that you have a dream to fulfill. Sometimes it seems impossible, but there's always a chance, even if it's very small.
A few years ago, I wanted to continue my studies, but no matter how hard I worked, I couldn't afford to pay for private college and continue. So, I researched the requirements for public universities and patiently waited until I was able to enroll.
Also, as you mentioned, there are several online training programs that can help you acquire skills that can help you get a job.
I wish you success in everything!
