I think that people are forgetting that nobody outside of comic book fans cared about "Iron Man" when the movie came out, and what's more, RDJ was not a box office draw at the time. That film became profitable because of positive reviews and word of mouth.
As for Robert Downey, he was not Iron Man at the time, he was playing Robert Downey Jr. more than he was playing Iron Man. The statement I am Iron Man at the end of the movie was prescient because now people identify Iron Man as having a certain personality that the character did not have before RDJ played the character.
