As someone who eats plant based, that is definitely not the case in the US. Gelatin is very easy to avoid.
Outside of jello itself, the common desserts that contain it are chewy candies and some mousse type desserts. So canolli, mousse, and flan frequently have gelatin, along with things like Starbursts and some chewing gums, but other than that I have not found it to be a common ingredient.
