I haven't independently calculated it, but I'd expect if M.S. was using 19:1 as the true odds it's because that's the ratio for all NFL games going back for something like 10 years.
The books offer 1:10 because the general public is happy to bet the 'yes' at 7:1 due to A) they don't know the true odds, and B) they like to bet rare events with big payoffs.
