Really good question. Meeting people in college is really important as it is never to early to start building your professional network. I would say that a key way of making connection is through internships. Internships give you professional experience, allows you to meet working professionals, and give you the ability to put things on your resume. As an intern it is totally normal to ask lots of questions and ask people for help and tips. This allows you the ability to establish relationships with people which can serve you later in life. If you have a good relationship with someone they will be more inclined to help you later in life.
Also, never be afraid to establish a working relationship with your professors. Professors are a great resource as they know tons of people, will gladly help you, and are often the best resource for student to utilize as they have much experience helping students. Do not just view your professors as people who are there just to instruct and teach you, you never know who they know and what tips they may have. I have had friends who were able to find jobs based off of what a professor told them/introduced them to.
I hope this helps and I wish you the best of luck!!
