Update from 3.0.0 to 3.0.2

Hi there. I tried to run composer update but it did not update the core which is still at 9.2.4 and commerce core that is at 2.20 when 2.30 is the suggested version (2.27 security update). Also a few other modules did not update (not part of the opigno distribution I think). What does it need to be done to get Drupal core updated? Thanks in advance :)
