Please be more careful when interpreting the Stack Overflow Developer Survey
You cannot say whether the difference between your sample distribution and the population is “statistically likely” or not without inferential statistics. If you did run an analysis using inferential statistics, you could make a statement about how likely it is that a distribution from a random sample of the population would have the characteristics that this sample does. Inferential statistics of SO survey data have minimal value in this context (comparing distributions to the population of developers) because respondents were not sampled using random sampling methods.
