Is it normal to feel scammed and fooled after graduating from college? Does it get better with time? Will I see some rewards after a while?

Graduated 1 year ago and it feels like a massive waste of time and effort. If I could go back in time I wont ever step in uni.

Btw Im not talking about jobs and opportunities. I dont see improvements in my knowledge and intelligence. Talking to people who didnt go to college I dont see differences, on topics that matter. Sure these people wont be able to size a batch reator or develop a fourier expansion to simulate heat exchange on a 2D metal bar. Who cares anyway?

On topics that matters, I cant really tell which was the contribution from college. I feel like most of my wisdow comes from aging and life experiences. Havent I wasted time in college, today, I would have similar knowledge/wisdow just because I have aged.
