Visitors NEGATIV List page "Subs"

I created an access level like wanted for visitors.
I created a negativ list and restrict diffrent pages.

for example "Subs"

But this page is still viewable by visitors. I only want it to be seen for members. cause I only want members to subscribe to my page.

Do I really have a visitors page?

Cause my mambers only will have access to 6 pages, theis own frontend to add posts.

If I understand right, I need to set the access level for visitors to every page they are not allowed to see in the negativ list.

And members are allowed to see everything. do I have to set a pöositiv or negativ list??

I dont understand that,
