I think the parent was correct in the use of the word "Risk"; it's different than your definition, which appears to be closer to "likelihood".
Risk is a combination of likelihood and impact. If "risk" were just equivalent to "likelihood" then leaving without an umbrella on a cloudy day would be a "high-risk situation".
A rational person needs to weigh both the likelihood and impact of a threat in order to properly evaluate its risk. In many cases, the impact is high enough that even a low likelihood needs to be addressed.
