No, but I remember seeing another recent poll about a year ago where the results were that about 20% of GenZ identify as LGBTQ.

This would imply that 10% is the acceptance rate (which has gone up “thanks to GenZ’s contribution”) and the actual rate is higher than this, but that part is missing from the information.

It’s UE in Spanish, from Unión Europea. (Non-doubled letters because it’s a single Union, there’s no plural like in “States”).

Sometimes people in Spain do use the English acronyms for both EU/USA, but I don’t think I’ve seen it often. Both UE and EEUU are more common from what I’ve seen, and also people rarely say these out loud, it’s exclusively a written language problem.
