Do you not need more data points to dispute it?

No. To support a blanket generalization, one needs to survey the entire
population. To refute a blanket generalization, one need only survey a
single member of the population, so long as that member is a
counter-example.

If you had ever studied statistics, you would know that is not true. That is
why sample sizes are less than population sizes, and how confidence levels
are relevant.
