It probably is in the record. He's just phrasing it casually.
You can very easily look at a graph of fatalities by age and extrapolate that if a 22 has a 99.99 percent of survival and a 70 y/o has a 10% chance of dying reduced by 93% for the effectiveness of the shot... the 70 y/o has a 99.7% chance of survival if vaxxxed... which is worse. But that's a lot of words. So, he says "I've heard.... (from my clerk who read the record and did the math)."
