Clearances can be made inactive, which is what usually happens when you leave an organization. You’re still cleared, you just don’t have access to classified info until your clearance gets reactivated.
Revoking their clearances (which is what the President is considering) is much more serious.

Not serious at all; just just. When you leave a job you leave your papers and lock the door behind. Your clearance is part of your job and belongs to your employer in a just world.
Your explanation sounds reasonable as I also wondered if their clearances were ‘activated’ or just ‘inactive’...and ‘Revoking’ would appear to indicate certain circumstances affects an individuals continued eligibility to hold a security clearance.
