Target Audiences for a wiki page does not have any effect

Question

I am working on an Enterprise wiki site collection , I have defined that only users inside a SP group named "owners" are the Target Audiences for a wiki page as follow:-

but currently all users inside the visitors and contributors groups are able to view & edit this wiki page .. so can anyone adivce on this please ? i though defining "Owners" as the Target Audiences for a wiki page, will prevent users that are not defined inside the "Owners" group from seeing this wiki page ??

Thanks

Audience is not equal to Security!

Audience on pages is mainly for showing / hiding the page from for example the current navigation, users will still be able to find and edit the page through links and site content for example
