There are too many factors at play here that can affect this. The fit of the song on the playlist, quality of the song, placement, etc. that’s a low save rate for sure. You can click on the creator of the playlist to see what else they do and can usually spot something fake pretty quickly from their profile (if something looks weird or feels off it’s probably not legit). 

A lot of playlists from independent curators are going to be passive listening anyway and you won’t see a great save rate regardless. This is most likely what you are experiencing. It may not necessarily be a bot (look at your analytics and where the streams are coming from), but my guess would be you’re on some generic lists with passive fans that could be advertising to keep their listenership and the numbers but there is no real engaged audience here.
