Orcas have notoriously selective taste preferences that tend toward nutrient dense fatty foods. They can eat anything and different pods will narrowly specialize in different types of prey, but it is quite apparently a choice based on regional preferences. These food preferences are passed down over generations. Not terribly unlike human cultures.
Orcas are very smart. Humans, even if we met their taste profile, are not a repeatable food source they can specialize in hunting. They may also recognize that eating humans comes with unknown risks because they are pretty observant of what humans are capable of.
