Is a three-year degree worth it or should I just start working right away?

Hi, I'm finishing my fifth year of scientific high school in Milano and I'm not sure what to do. My dad says that with a three-year degree in Computer Science Engineering I could find a job right away, but I'm wondering if it wouldn't be better to do a master's to have more opportunities. What would you guys advise? I've seen that starting salaries are pretty good anyway.
