Does standard Oracle users count in licenses?

When running the User Role Membership Report and see that there are a couple of users that we have not created and some of them cannot even be found in the Security console. I have researched these roles and understand at these standard generic Oracle roles. These roles include:

• FIISUSER
• OPAUSER
• PSCR_PROXY_USER
• octo_monitor

Do these roles count towards licenses? I would assume not, but would like someone to confirm whether this is the case or not.

Thanks in advance!
