Comments problem

problem in comments.php
at line 35 where it starts:
} elseif ( '1' === $comments_number ) {
its not work for translate. I think it should be as follows:
} elseif ( '1' == $comments_number ) {
i change and it work now.

in twentynineteen its :
if ( '1' == $discussion->responses ) {

is that problem or not?
