"There are about 300 billion stars in our galaxy. About 10 percent (or 30 billion) are roughly Sun-like," he explained. "At least 5 percent (1.5 billion) but possibly as many as 90 percent or 100 percent (about 30 billion) of these have Jupiter-like planets."

Um... 5-90%? That's kind of a big margin of error, don't you think? ;)
