I would emphasize also, like you said, that the turnover is really low. You don't need 10 accountants when you have 70 people in your company.
I worked for Ubisoft for 10 years before Larian and yes, obviously, a company with 8000 people with countless studios and making above 1 billion each year, needs a lot of them. So is EA or any other big company.
For small companies, you need only one I would guess and for even smaller companies (I've a few friends working on their own with few people) it's outsourced.
So I guess, sadly, you really need to be "lucky" to find a job like this because it's so rare.
But don't lose hope mate, you'll find one some day ^_^
