Yes, you can change your career if you have the passion and you work hard. More than a little bit of luck also helps.

I studied corporate finance at university (including to Masters level part time while working). Did well in the investment banking arena over a 10 year period (including being a Director of a subsidiary of a listed company).

Went travelling for a few months, came back and whilst contracting decided to build a SaaS. I had almost zero programming experience outside of VBA. This was at the age of 38.

I ended up with 5 SaaS companies (some more successful than others), plus started my own software consulting business (grew to 8 employees). Also had 2 kids in the meantime.

I'm now head of Engineering at a ~100 person company.
