To be maximally fair to their argument, I think it is good to point out (not that it's the point that was made but that it's a good point to make) that 9,100 is a distinct departure from 0 when there are other numbers in the tens and hundreds. It's worth questioning the disparity and whether it's indicative of incorrect or misinterpreted data.
Not sure why I decided to comment specifically on what you posted given the fact that there are various levels of misinformation going on in this thread, but I guess yours is the most blunt.
Anyway read the article you linked to again, you completely misread it.
There are 300~350 thousand Jews from Iran, but only 9,100 are estimated to still live there.
