Credit scores aren't a score of how valuable you are, they're a score of creditworthiness or how unlikely you are to default on a loan. The largest factors are age of credit and payment history. Utilization is also a factor. Someone who occasionally misses payments and has high utilization is going to be more profitable but higher risk to lend to.
Just because that’s what a scores is designed to do it doesn’t mean that’s what businesses use it for downstream.
The fact people always debate what a credit score really means suggests that there are too many factors rolled up into a single number when we should really have a few distinct sub-scales. Anybody that has made a dashboard for a ceo with a short attention span that refuses to deal with nuance and just wants to see “a number” knows this problem all too well
