People argue about these specific numbers because frankly it's a hard population to get honest surveys of, but here's one I found.
https://pubmed.ncbi.nlm.nih.gov/9698636/
>As adults in prostitution, 82% had been physically assaulted; 83% had been threatened with a weapon; 68% had been raped while working as prostitutes;
...
>Eighty-eight percent of these respondents stated that they wanted to leave prostitution, and described what they needed in order to escape.
If those numbers are even close to reality I think it's hard to argue that the negatives of prostitution don't far outweigh any positives.
That said I think it's not at all obvious what the solution is here because clearly criminalizing prostitution is ineffective at eliminating prostitution.
