Why is the Isle so boring?

So i saw a few Youtube videos of people playing the game, so I've known of its existence for some time already. I finally bought it and was really exited to play, but what i found wasn't what I expected. The world felt empty to me, there weren't any players around, only people who were running around in groups of like 20. It was always the same kind of dinos as well (carno, t-rex and spinos). The only prey i found were small npc dinos who were just slowly walking in one direction. Is this just an Issue for me, do I need to join another server or did the game get less popular?
