I don't think so.

The current world paints queer people as exotic and abnormal most of the time, which is due to representation being so low and most importantly hidden away.

For example Disney, where most kids get their movies from, scrapped Nimona because there's a gay couple in the main cast, and Netflix picked it back up. How many headlines have we had that the first Disney movie with a gay couple is going to happen, only for that gay couple to be 2 people that pass more for very good friends or might just be in the background.

And Netflix isn't that great either, scrapping lesbian shows the moment it becomes obvious. Famous example being Warrior Nun. They admitted to making the first season straight bait so they'd get a second season after which they've been cancelled. Don't get me wrong, Warrior Nun wasn't a qualitatively great show but we lesbians loved it, because we're so starved for shows with representation, and it made Netflix good profits.

Most of queer representation has to be specifically seeked out which is exactly what's wrong and leads to the assumption that everyone is cishet.

So yeah in a world where most kids assume they can't be queer because there's normal and there is queer and they are just a normal kid and being different is scary it can be assumed that official statistics are not representative of the actual percentage.
