Indeed. Depending how one defines "heterosexual," 90-95 percent of a typical human population is heterosexual. Hence, 9 out of 10 to 19 out of 20 characters in a fictional universe might be expected to be heterosexual, unless they are being selected for unusual sexuality; furthermore, if one does not know a character's sexuality, "heterosexual" is the logical default assumption.
