When someone says "great white" they are probably referring to Great White Sharks. Great white sharks have been around for 16 million years, so some may call them ancient, and, of course, they still exist today.
We are at the top and great whites are one notch down from us

Humans are not part of the great whites prey
Great whites will eat anything in sight.
No
Great whites need their great sense of smell so they can smell their prey or so they can smell blood.
Adult Great Whites are apex predators. Apart from the Orca (Killer Whale), there are no known predators that may attack or kill a Great White. In regions where both the Orca and the Great whites inhabit and compete for food, Orcas may attack and kill these sharks. Since Orca's are much larger than them, they can attack and even kill great whites.
