code :
delimiter //
CREATE TRIGGER catchUser BEFORE INSERT ON defaultdatabase.users

should help you out Statements in your script gets executed in the sequence of their appearance.
For the trigger to fire, you have to execute the INSERT statements on users post creation of the trigger.
code :
-- Triggers `users`
CREATE TRIGGER `Insert_Into_Classes` AFTER INSERT ON `users`
 -- write trigger body here

INSERT INTO `users`(`id`, `name`, `studentid`, `team_id`) VALUES 
(1,'User Name',1111,1); // this goes on for 127 names
