That's not really true. Orcas are one of the most widespread species and are almost always associated with coasts. The reason for difference of attacks is biology and intelligence. Sharks are basically one big system of sensors, and they attack basically anything that triggers those sensors. Orcas have a much, much higher intelligence (on the level of humans, in my opinion), and so they probably see humans the same way we see sloths. That is, we're curious about them, but they would make for a nasty and rather pointless meal. Orcas also have generational memory, so for certain pods, humans are probably known to them and they'd rather not directly engage.
