I believe you could end up being in any of those positions you listed. I would suggest you set your goals on something realistic, say regional captain, and you may well end up going further!
Remember aviation is a highly cyclical industry. Everyone seems to have their ups and downs along the way. I'm still in my twenties, but when I started, I had to fund my own training which meant full time work, uni and flying at the same time. For this reason it took 5 years to finish my training, which looking back now was a long time. It didn't help that flying schools kept shutting down or instructors were useless or the wettest summer in history would arrive when I'd organised annual leave to fly... There always seemed to be some hurdle to jump. But I still loved the journey.
Funnily enough things suddenly turned around for me. I went from GA to international widebody F/O in only a few years. You could be the same!
If you love doing it, you'll always be happy. Good luck!
