Hello @Bill_Ymr_61
Greetings!
If they are empty updatesets, then you can go ahead and delete them.
But non empty update sets,
ServiceNow strongly recommends that you do not delete sys_update_xml entries, because this action:
Does not undo the updates.
Removes any record of who applied the customizations.
Removes the sys_update_xml entries associated with the update set, so customizations are overwritten when the instance is upgraded.
you can also consider moving the Changes to default updateset and emptying the updateset before deleting them
refer:

Please mark the answer as correct solution and helpful if helped.
Kind Regards,
