It really is astounding how many people overinflate their IQs. Many people regularily claim 140 and higher. A genius level IQ is rare for a reason. Extremely few individuals truly possess it.
This can lead to a form of confirmation bias: Since genius level IQs are rare, then any claim of such is automatically discreditable.
Also, there are a few other things that impact perceptions of self or others as having or lacking intelligence. A major one is the Dunning-Kruger effect, which says that the less competent someone is, the more likely they are to incorrectly perceive themselves as competent and incorrectly judge others as incompetent or less competent in comparison to themselves. Another is imposter syndrome, in which people find it difficult or impossible to internalize their accomplishments and do not believe they deserve the success they have achieved.
As for myself, my IQ was tested in the genius range, but I have a lot of difficult determining whether people are more or less intelligent than I am, and often when I want to think they are less intelligent, it is because they disagree with me over something, not necessarily because they are less intelligent. People can also be intelligent and mistaken or ignorant about particular topics. Or they can come to legitimately different conclusions.
I know that IQ doesn't measure a lot of things (such as adaptive behavior, self-care skills, executive function, etc) which mitigates many of the supposed advantages having a high IQ might have. I am personally dubious about the worth of such tests as they do not seem to communicate information that is actually of use to me.
