No, the number is an arbitrary choice and the test results of IQ tests are scaled so that they fit into the distribution, based on random sampling of the population when the test is designed.
IQ is not a linear scale, all it tells you which quantile of the population one falls into. It does not describe the relative strengths between the quantiles in particular tasks.
To figure that out there are additional surveys that map IQ ranges to occupations and the tasks an individual is required to perform.
