Fake/Automated/Scam

Called me at nearly 9pm, was an automated pre recorded message saying last attempt at contact, I had won a sweepstakes to stay at a hotel for free and to press one.(it never said what happens if you press one) .Then it said press 2 to add to do not call list. I hung up thinking it’s likely a scam or something fishy, as I have never entered a sweepstakes nor did I recognize the name of the hotel.
