Chances of getting in

Being in the military has always been a dream of mine but never had the chance. I’m a newly PR with a masters in finance and a few months of warehouse experience in Canada and a certificate in cybersecurity. I just applied and here’s my 3 choices in order:

1. Cybersecurity
2. FSA
3. Logistics officer

Hoping for the best. What are my chances? PS. I’m 39 and in very great shape
