Are all pools closed for the season?

So we're heading to Vegas end of November. We booked the Flamingo. We saw a TikTok where the pool was destroyed (under reno), so we called to see what's up and we're told it would be ready by next year. When I asked about the poolS, I was told they were closed for the season.

Are all hotel pools closed that time of year, or did I win the unlucky jackpot with the Flamingo?
