Hi Antoine,
The main answer to your questions is that the data model of Wikidata
defines a *data structure* not the *informal meaning* that this data
structure has in an application context (that is: what we, humans, want
to say when we enter it). I try to explain this a bit better below.
as a suggestion, you can turn these kind of numbers into a probability
distribution using the beta distribution. If you use (1,1) as a prior you
get something like beta(251,1) for the the probability of the probability
that somebody named Aaron is male.
