Aren't crocodiles or Komodo dragons actually living dinosaurs?

I don't know much about biology or animals, but
In my personal opinion,
‌crocodiles and Komodo dragons just seem like living fossils.
Among the reptilian predators remaining today, they are the largest and most ferocious(?).
While we can't actually see dinosaurs,
looking at crocodiles or Komodo dragons allows us to imagine them to some extent.
To add a side note,
people who have eaten crocodile meat say it tastes like chicken.
Interestingly, they say chickens and dinosaurs are closely related.
According to modern taxonomy, they are considered a type of dinosaur.
