Maybe, but already two years ago, if you read the fine print for ex. by buying a ticket for Cirque de Soleil you accept they can use your face on the video for ai training.
But somebody did buy the ticket for you. Today you accept a lot when buying a ticket. Mostly you accept also to things like, they can use your picture on commercials / media and so on. Just the next time, take the time and read the full EULA when buying a ticket from a large event.
