"There are many URL's but we should not match with the string (wt)."

The following solves your problem - as stated.

$ perl -Mstrict -Mwarnings -E '
    my @urls = qw{
        https://www.abc.com.wi.pr.com/
        https://www.abc.com/
        https://www.def.com.wi.pr.com/
        https://www.wt.com.wi.pr.com/
    };

    for (@urls) {
        say unless /wt/;
    }
'
https://www.abc.com.wi.pr.com/
https://www.abc.com/
https://www.def.com.wi.pr.com/
