Which tech jobs can you realistically get by learning online without a degree?

I'm 28 years old, and to be honest, I haven’t done much with my life so far. Recently, I stumbled across programming and cybersecurity online, and the positive aspects of both fields really caught my attention. I’ve always been patient with solving problems, and I actually enjoy figuring things out. It gives me a sense of accomplishment. I'm also fairly tech-savvy, and for the first time in a while, I feel like I might have found something I could be genuinely good at.

The thing is, I’m not in a position to go to college or attend any formal institution. I’ve seen stories about people learning online and breaking into tech, but I’ve also read a lot of negative takes. Even graduates sometimes struggle to land jobs.

So I’m genuinely curious: if I commit to learning and work really hard, do I realistically have a chance to turn my life around and get into programming or cybersecurity without a degree?
