What does Daniel 7:20 mean?

I also wanted to know about the ten horns on its head, and about the other horn that came up and pushed out three of the original horns. This horn had eyes and a mouth that spoke arrogantly, and it looked bigger than the others. Daniel 7:20 - Modern Text Bible

(The ten horns represent multiple rulers or powers, and the new horn is a particularly boastful and dominant leader who replaces others.)
