That's not what it means amigo...it means Josh Allen threw 461 passes and 7.2% of them were dropped, which equals (roughly) 31 dropped passes.
Prescott, who threw 596 passes, had receivers drop 6.2% of them, which equals roughly 36 drops.
To summarize, if Josh Allen had thrown 596 passes (same amount as Prescott), we would expect him to have 43 drops, significantly more than 1 drop every 100 passes.
(usually a bad thing when the guy who's bad at math is liking your posts btw lmao)
