I’ve never referred to my university as a college.
I attended a two year community college, which I always referred to as college, and a four year state university that I always referred to as university. Otherwise, I referred to them by their acronyms, or more loosely as school.
But in the US, colloquially every 4 year school is a college. People say “I’m going to college.” People don’t say “I’m going to university.”

Sometimes it’s not just us Europeans who forget that the USA is a fucking huge place ;)
