I input some text I found off a random NBC article I saw posted to reddit and its likelihood is also listed at quite high.

> A 6-foot-6 Florida high-schooler pummeled a female school employee, leaving her unconscious after she confiscated his Nintendo Switch, according to police and video surveillance of the attack.

> The attack happened Tuesday at Matanzas High School in Palm Coast, according to the Flagler County Sheriff’s Office.

> Palm Coast is about 35 miles north of Daytona Beach.

> The 17-year-old student is 6-foot-6 and weighs 270 pounds, officials said.

> “The student stated that he was upset because the victim took his Nintendo Switch away from him during class,” the sheriff's office statement said.

Now, I don't have proof this wasn't AI generated, but I think its more likely that the tool just sucks. We have to remember that these dull, flavorless articles that are written en-masse are what comprises a huge portion of what ChatGPT is trained upon; so while the tool may be useful for determining other types of text, I imagine it'll have a high false positive rate on these generic types of articles.
