It must be a confusing and scary time for you. I'll try to offer you some words of encouragement, without knowing your situation or really having been in it.
I don't think a person's life outcomes (normally) are determined largely by one single decision. It's more about the habits you form and the knowledge you develop gradually, on a daily basis, over a long period of time.
It seems like you're wise not to just rush into university without being certain about a course. One question - does the university offer courses that can be used as credit for multiple majors? Could you choose a course that you find moderately interesting, which could allow you to jump to a different major? I guess what I'm thinking is, you could try one course just to dip your toes in something, and then from seeing how that went, you would have a clearer picture of what interests you more and then steer the ship more in that direction. It could take a while, maybe a few courses, but if you end up in a course that you really find interesting and engaging, then you've struck gold, and that can be come the foundation for your career.
You mentioned you really want an apprenticeship. Maybe that's a better path for you than uni. What is it that an apprenticeship brings to your mind? Would you like to be working alongside other people? Do you prefer to be doing rather than just learning? Do you want to feel part of something or connected to something?
I guess my 2c (I might be wrong) is that you're still learning about yourself and searching for your real calling in life, for what on a day-to-day basis you would get satisfaction out of. I think if you can find that, and marry it up roughly with a career (doesn't have to be a perfect fit, just approximate), then you're a success.
