You need to set aside a whole day to research on this site. Use the search facility to look up 'sponsorships', 'university', 'integrated vs modular', etc. As you learn, you'll discover more subjects to learn about.
There are very few sponsorships available in the UK just now. Most of those that do exist require a considerable financial contribution from the trainee. You need a great deal more understanding of how these things work before you attempt to make a decision about whether or not you should go to university.
There are no easy routes into flying for a living!
