Almost certainly these people know way way more than you and a lot of knowledge is tacit knowledge and cant be explained easily.

Also don't trust anything from college that are not hard provable facts. Just don’t. Trying to learn "best practices" in college is total BS.

For example, I was already quite experienced when I worked with a specific really good older engineer. I knew he was very good but I thought he was wrong about some things and I was right. We had some debates. I kept thinking about those things for years. Now I know he was right about all those things. Yeah, he was right about everything I remember disagreeing with at the time. Took me years to figure it out.

So here is an advice to my younger self: Shut up and put in the thousands and thousands of hours first.
