If you do go to University make sure it is something you really want to do and for the right reasons. It would be a waste to spend 3 years looking out of the window at every aeroplane that flies past and thinking I would rather be up there
If you have your heart set on flying then flying is what you must do. I would say try to create as many options for yourself as possible - study something aviation-related, join the University Air Squadron, work/save for some flying hours yourself, and also apply to any (part)sponsorship that is on offer.
If an opportunity came along to fly full-time then I wouldn't say no. You can always take up/continue the studies once you are employed as a pilot... it would give you another goal to pursue then.
Remember that people always have 20/20 hindsight with whatever advice they give and those who were fortunate enough to start in aviation straight from school will, like the rest of us, at some point think that maybe another route would have been better for them....
Whatever you do good luck and keep us posted!
Cheers
