Question on "ModifyCustomField" Rights

To list,

Back in 3.6 X days, I believe that the only way to “See” or “Modify” a
Custom Field was by granting that right to a group while in the
Config->CustomField screen. I could be wrong, but at any rate, I remember
granting rights to a lot of CF’s that way.

I now have 3.8.7and I see these rights while in Config->Queues->Group

What’s the difference? Does one take priority over the other?

Thanks in advance.
