You don't need a degree to get a job in tech in your 30s with work history on your resume. You also don't need a degree to learn things. There are so many courses from top colleges online for free today, and other learning resources too. All you need is motivation.
In my experience, motivation comes from interesting work. If you need to learn to make progress on a project you care about, you will learn. So what you need is a project that requires you to learn the things you want to learn.
