The T. rex would be liable to do so after the initial scene where it escapes and eats Gennaro, but the raptors are likely to behave more like wolves and roam around hunting for prey items. Depending on location and circumstance, it’s not unreasonable to think they’d go after humans, seeing as we look pretty defenseless, and we know Velociraptor would hunt animals a bit larger than itself, given that they hunted Protoceratops.
Dinosaurs are hardly familiar. We know they existed, but they’re not a part of the world we live in, save for birds. Sharks are a bit more familiar, but because they live in a totally different medium, we rarely have to deal with them. That’s why so few people are actually killed by sharks.
