Yes, as with knowledge and belief. A person's knowledge is not determined by actual facts, just facts-as-they-perceive-them.

The differences are that people have very strong intuition and emotion around risk, and that risk is not directly observable. So unjustified confidence levels (high or low) about easily measurable things are even more common and understandable than unjustified belief about easily measurable things. "Knowledge" is a prejudiced term in this respect: there's not really any such thing as "unjustified knowledge".
