If you've never worked in tech before, but have a mathematical/analytical brain (or a very logical thinker) you could try a coding course initially to see how you would enjoy being a software developer. If you enjoy the free courses online, enroll in a coding boot camp which is very intense but is a pathway to becoming a junior developer. It is competitive but age won't hold you back. This role can also be called software engineer but you don't need an engineering degree.
If you're more creative/artistic, you could become a website/user experience designer - also needs you to learn certain tools/application/software and get a certification in it.
If you're organised and task oriented you could go into technology project/product management. An entry level role would be a technology project admin or co-ordinator. And you'd work your way up learning project management techniques like either waterfall (outdated but some organisations use this) or Agile (much more useful). Once you get to project manager level or product manager, depending on experience and industry, the pay is good. Especially if you freelance and on a day rate. This still needs you to learn how technology infrastructure works together, basics of software development (free online courses) and how to manage people.
Solution architect is the other option - this is harder to get into as they tend to start off as developers and work their way up.
IT operations is normally the lowest paid option. This is help desk stuff and managing hardware (laptops, keyboards etc) and software request for a company. Much easier to get into, you'll learn about how tech depts are run, and you can move into the project space eventually.
