LOL they know their math... basically he's saying the probability of making profits when buying is 20%, and the probability of making profits when selling is 80%.
Some of us love to gamble, we like the 20% probability because of positive expectancy.(Yes NVDA)
My point is that buying options suck as the title suggests when you take into account the probability of making profits versus the risk.
