FWIW, I am also in training and struggling to make ends meet. The financial burden that comes with becoming a pilot is huge. I had good career prospects in hotel management, but decided to pursue a dream that has been with me since I was a child. I often wonder if I'd made the right choice (I started training 'late', I'm 28 now and on my way to my CPL), but then again, I can't see myself doing anything else for work but flying. I know I would rather regret trying than not trying.
If you want security, go for the Uni and IT job. If you get a 9 to 5 Monday to Friday IT job, you'll probably be looking out the window of your office wishing you'd become a pilot.
If flying is really what your heart desires, than that is what you should do. Even though the odds are against you, with determination, you will succeed.
Best of luck whatever you do!
