On-campus jobs and internships

I am an international undergraduate applicant for a CS major. I am sure I will get some scholarship from the universities I applied to. I’ll also work part-time and do paid internships. As I want to take a minimum student loan, how much do you guys think will I be able to cover on my own? I saw online that many companies like Capital One and Uber pay around $7000 per month for three months. And on-campus jobs can pay as high as $12 dollars per hour up to 20 hours per week.
