Advice on strengthening CV

I am Turkish 17 years old. I am considering universities in Ireland, Poland, and Estonia, and I'm interested in cybersecurity or computer science programs.

​To improve my CV in the cybersecurity field, I've added a Python port scanner and a file crypter to my GitHub. I'm currently earning IBM's cybersecurity and Linux certificates on edX, and I'll also be getting the Google certificate from Coursera. What else can I do to attract the attention of universities and employers?

What should I do during university? Is Hack The Box and TryHackMe enough? I also want to earn money, and passive income would be even better
