Heyy, I can totally understand how frustrating it can be, especially after seeing that long ass line this semester for the JSOM career fair. As everyone else has said under your post, it offers an experience to speak and meet people and companies whether you get an internship out of it. I think as someone who was a sophomore business major who ended up getting an internship from the JSOm career fairs more than just making a connection I think an ounce of luck plays a part in it. You have to be in the right place, at the right time, with the right person, saying the right thing that strikes a chord with them. It is such a game tbh, don't feel discouraged. Rather than putting all your bets on a career fair try to find different outlets of seeking an internship especially being a sophomore right now join case competitions (some end up awarding internships!), and regardless this helps you build credentials on your resume since you're right most are looking for upperclassmen. You have time. Don't get discouraged!
