By the same definition every helicopter, plane, kid flying a drone, even car on the road is not “safe.”

It’s the same way I can call a system reliable when it is 3 9’s, but that doesn’t imply 100% guaranteed uptime. Or a statistician can reject a hypothesis that has a low enough p-value but still more than 0. Or how health systems and procedures are considered safe above a threshold, or how we consider condoms safe sex while understanding they are not 100% effective.

I’m finding it frustrating that when it comes to UFOs, people tend to isolate the most remote possibilities.
