Interpolation occurs between double quotes or qq and is not involved here (and would not affect the outcome if it was).

Placing quotes around characters makes it a text string, and for false we would need an empty string or a single zero: anything else is true. Numeric zero (with no quotes) is false:
use strict;
use warnings;

if ( '00' ) { 
    print "Yes\n"
} 

if ( 00 ) {
    print "Yes\n"
}
else {
    print "No\n"
}

Gives:
Yes
No

Update: correction to wording of a false string.
