Credit card statistics are heavily manipulated because it's easy to make them sound terrible. I don't know which factoid specifically you're referring to, but the studies about "X percent of Americans couldn't handle an emergency expense without putting it on a credit card" often use tricks like including anyone who would pay by credit card if they could. I remember reading some of these studies and realizing that I would have been included in the statistic because I prefer to use a credit card where I can, even though I pay it off before interest accrues.
