Well we are somewhat in a similar boat … I’m 31 but finishing up my CS BS degree this winter. Nevertheless, I can tell you that I have seen people as old as 45 at our university so it is never too old to start.
Next up, it depends what you want to do in tech, do some research to see what you would like to get into too, and see yourself doing for LONG periods of time. Web dev, SWE, A.I., ML? Get into something you are passionate about!
Lastly, stick to one programming language and master it. You want to understand the concepts, and when you do… this will carry over to any other programming language with ease. From my experience if you start with something like Java or C++, everything else from there is relatively easy to pick up. Though you don’t have to go this route but thats just my op. Nevertheless, FCC has that python section added and it looks promising you should look into it.
