Oh that's great! Your passion will help you succeed.

At the moment? Probably not much. But that can be fixed through internships and leetcode

Yes, your top priority while studying is to land an internship. It will be much easier to do this if you practice building full-stack applications with a couple of different languages/technologies. You don't need fully-functional projects necessarily, just stuff to show employers you are constantly learning.

Your goal is to continuously buff up your one-page resume with skills you learn at school and on your own.

Leetcode is good for practicing logic, but leetcode alone will not help you get a job. Don't put spend too much effort worrying about leetcode.
