Uncle that I don’t know asking me to get his son into college?

I don’t understand why he would feel comfortable asking this? I was a little lost for words when he wanted me to help his son get into school. I’m a professor at a university. I have no control over administrative work. I can give advice and that’s all. Am I wrong to feel uncomfortable, or like this man only cares about his son and bettering his son.
