I have gained a lot. Generally, college students have little social experience and don't understand many things. By trying different part-time jobs to exercise your interpersonal skills, and then earning money by your own hands, you will have a sense of self-confidence and pride. If you make more money, you can have your own financial management concept in advance, which is helpful for your future career planning. And you can buy what you like, which is of course within your power.
