Is low IQ a limitation?

I have been practicing the online raven test for 10 years, but 2 months ago for the first time a psychologist gave me that same test and I got an IQ of 80.

The test did not seem so difficult to me because I already knew what it was about but I still got that result, The psychologist told me that this does not limit me at all and that the safest thing is that I actually have an average IQ, I have always had problems learning to understand things and get along in life and work, I do not have much creativity, I'm bad at any mental task, I'm a slow learner, in school and high school I was always behind, and at work I'm also behind I don't understand things that are explained to me, the only jobs I do well are those that don't require thinking and making decisions about repetitive and routine jobs, I was never interested in studying, I only learned by heart so as not to fail and that was enough, and I was never interested in going to university.
