Most people see only the "in game" of wing chun because that is how it is different from most martial arts. People never get around to showing the pole form and how certain techniques within that form can add to wing chun's "outside game." It isn't all about close-range fighting because not all fights will begin in the range where most of wing chun takes place. However, if you train right, then you will train to get into the range you need...just like grapplers train to get into grappling range, boxers train to get into punchin range, kickers train to get in kicking range.
And if you are fighting someone who is comfortable in one of those other ranges, then you try to get into YOUR range while keeping them OUT of theirs.
Every martial art trains that way...or at least, they should.
I don't know why people assume wing chun has this narrow training methodology where we fight only "in the pocket" or only at trapping range or whatever other misconception they have about it.
