You make it sound like I claimed that people not working at google are less intelligent. My point was that if you are already making good money you are not looking for lottery tickets to buy.
The total sent is (at the 494,170.68/1492=331.214 rate) almost exactly 500,000 US$ (499,821.59) of which, in four operation of 373 Eth each 1492 Eth were withdrawn 494,170.68.
Of the 212 total operation 4 are withdrawals, 3 are 0, that makes 205 "IN" operations.
The distribution of the amounts of the single operations/deposits is interesting, I quickly put together a few "classes":
a. >30,000 2 Total 66,243 US$
b. 20-30,000 3 Total 70,840 US$
c. 10-20,000 6 Total 82,803 US$
d. 5-10,000 14 Total 102,576 US$
e. 2.5-5,000 23 Total 80,125 US$
f. 1-2,500 33 Total 54,225 US$
g. 0-1,000 124 Total 43,010 US$
If the "targeted audience" was around 9,000, roughly 200 or 2.2% fell for the phishing.
A handful of people (classes a., b., c., 11 in total, i.e. coincidentally roughly the 0.1%) contributed for almost half the amount 66,243+70,840+82,803=219,886 219,886/500,000=43,98%.
