Best of luck for your plans.
Sponsorships are few & far between, so it's best to assume you WON'T get one.
Aviation is a very fickle industry and I always advise a backup plan, I have used my own a couple of times.
I STRONGLY recommend that you do go to university. This will give you a degree which opens doors and serve as a backup career job. Also, while at University you get the chance to join the Air Squadron if you wish.
IF a sponsorship then comes along you are even better placed (with a relevant degree) to get your CV to the top of the pile.
I don't want to start an English debate but you should check the use of advise & advice, no spel chicken will sort this!
