“More than 8,000 fans cast ballots for Dragon Award winners, selected from among 93 properties in 15 categories covering the full range of fiction, comics, television, movies, video gaming, and tabletop gaming.”
Last year’s press release used the same wording but said “10,000” https://www.dragoncon.org/mediarelations/2019/09/02/dragon-awards-recognize-fans-favorites-in-fiction-games-and-other-entertainment/
