yes, reference to an array (pointers are in C memory addresses but references are more complicated).
But it doesn't matter @array and $array_ref=\@array are just two different ways to represent the same array.

As I told you: No!
You are pushing to a variable starting with @. If the array doesn't exist already it will be allocated. If it exists but it's incompatible to push (like a hash) you,'ll get an error.
In newer versions of Perl you are even allowed to push directly to $array_refs.
