Tomoli, take a gap year. You don't have to do the round-the-world thing if you don't want to, just do any old job.
There really is no rush. You might be at work and think it's great and want to carry on. Or you might hate it and long to have a bit more freedom and less structure, and embrace uni with open arms next year.
I loved my course at university and, having worked for several years, I would gladly go back tomorrow if I could - I think work, earning, mortgages etc are seriously overrated! But everyone's different. The main thing is, there is absolutely no need in the world to rush into anything.
Don't get hung up on either what everyone else is doing, or some notion that you might get ahead by not going to uni. Do what's right for you.
