It’s right, though. For a worst-case scenario, look at the number of Americans who died in terrorist attacks in 2001: 2819 killed in the September 11 attacks, five killed in the anthrax mailings. Total US population is about 300 million. Some simple math shows that 99.999057% of Americans were not killed in terrorist attacks in 2001. The numbers are even better if you look at a year other than 2001, or an average over several years.
