Key information:

There’s roughly 100 firefighter arsonists convicted every year in North America and all of them are serial arsonists, which means three or more fires,” Nordskog told CBC.

According to Nordskog, firefighter arsonists tend to be young males who recently joined the fire service, who may become bored, desire recognition and struggle with anger or frustration.

All things considered, it’s probably a smaller percentage vs. doctors doing un-doctor things, cops, etc.

There's roughly 200 doctors convicted every year in the U.S. alone of criminal 'patient abuse or neglect', for data compiled between 1988 and 2026 [1]. While I'd prefer to cite the 'patient abuse' figure since 'patient harmer' is the most equivalent behavior to 'firefighter arsonist' (both cause the problem they treat), I think it's worth remembering that human beings — regardless of their profession — have a slim but non-zero chance of deciding to create problems that give them professional satisfaction to solve.

This may also be subject to survivorship bias, and there may be a portion of firefighter arsonists who escape prosecution or conviction

So, the number '100', has to wildly low, as some arsonists will not have been caught, or only started one or two fires.

I don't think you can extrapolate it to every profession lol. Even in your example, doctors and cops face much more scrutiny and doing an "undoctor" thing can mean your career is gone. It is far easier for them to comit arson tbh than do the equivalent opposite of their profession's general aims
