There have been a small number of cases where wolves attack humans because 1. Humans have spent centuries exterminating wolves anywhere humans regularly go. 2. Humans adapt their behavior to minimize the risk of attack by wild predators. This is like saying "relatively few people get mugged wandering around alone in the tenderloin at 3am". It's because everyone knows it's a terrible idea and avoids doing so. That doesn't make the area safe.
