Mysql ORDER BY ... DESC

Hello ! I am because I need your help, logic lol. I've created a ranking system with points, so far so good, I'm using MySql and here's my query : SELECT * FROM classementquizz WHERE serverId = "${interaction.guildId}" ORDER BY points DESC But there's a problem: MySql isn't sorting the points correctly, so a screen will be attached. I heard that 15 is less than 2, I didn't know.. haha. I don't really understand and I can't find my solution. Thanks a lot!
