I think its somewhat of a determining factor, but there are cases where there were mediocre-bad callout scores and decent-good numbers in terms of sales/streams:
In instances such as
We Can't Stop, Chandelier, Gangnam Style, GDFR, they had bad callout scores, but their sales and streams were pretty decent or excellent. As a result, radio kept those songs around as much as they could, but they were quickly dropped (or free fell) once they reached their ultimate peak.
We Can't Stop was nearly dead last, if I recall. However, we all know that it had amazing streams and great sales (being nearly top 5 on iTunes throughout the summer). Thus, radio didn't really have a justified, valid reason to let it completely go. As
Worth It is doing well on the sales and streaming front, I think it kinda falls into this category. Radio will continue to play it. There's always a chance that scores can improve, too.
Want To Want Me wasn't doing too great, but now, it has one of the highest callouts. Maybe that can happen for
Worth It.
On the flip side, in a much more recent case, such as Bills, it had bad callout scores, bad sales, AND bad streams. Therefore, radio had no reason to play it at all seeing as no one was interested.
Sorry for the essay 
I'm quite sure they were alive when Shaggy was slaying with back to back reggae-influenced #1's over a decade ago. In fact, Shaggy's name might be a major reason this song even got noticed and played on pop radio.
. I bet only his radio station is playing it 
And Worth It so low? Why are callout scores even relevant?
