Correct. I believe IQ is meaningless with regard to Einstein. People with Einsteins genius are extremely rare.
When he first presented his General Theory of Relativity only a dozen or so people couldn't even understand it. He was a true rarity.
That is a misconception that even Einstein fought his entire life. It was largely based on a misreported story by the New York Times. Arthur Eddington, the British physicist who attempted to use the eclipse of 1919 to verify General Relativity, took advantage of this misconception. According to Eddington, after he presented his results to the Royal Society a member of audience approached him, saying, "I understand that there are only three people in the entire world who understand this relativity business." Eddington stood speechless for a moment, and his inquistor insisted, "Now, don't be so modest, man!" Eddington snapped out of reverie and replied, "No, I'm just trying to think of who the third one might be!"
Eddington retold that tale at high tea in Oxford for decades.
Einstein's son, who became a professor of civil engineering at Caltech, insisted that his father's distinguishing trait (a lot like Richard Feymann) was his absolute refusal to take anyone's word for anything. He would not accept something until he had thought it through for himself.
I watched a program on cable TV recently about Einstein. They said he took a job where he would have time to just sit and think things out. If I just sat and thought I would fall asleep. I need to move around and do things but not things like math and science LOL!
