They are comparing apples and oranges. First, these are different sports.
Second, they are counting the viewers IN THE US between two games, one of which had the US playing and the other one didnt.
I recall the stats some people showed claiming the US women's team deserved better more money because of the audience they atracted and supported these claims with stats, figures, the lot. Long story short, they were comparing the US women's team stats from a world cup year against the US men's team in a non world cup year.
You need to be very, very, very careful when you read these things. 90% of them have an agenda and therefore tons of cherry picking and 99,9% of the authors could pass a statistics 101 course if their lives depended on it.
