That conclusion does not follow from the numbers given. In fact, the chart as a whole leads one to the opposite conclusion.
The breakdown of people with more than 9 partners is
Women 11.6+12.9=24.5
Men 12.5+28.3=40.8
All that said, I presume that in such a discussion a higher body count is considered "better." That by itself should tell the participants how lost they are.
Furthermore, the numbers exclude same-sex sex and thus reflect a heteronormative bias. Only sex with the opposite sex is sex. Really?
