What secret state do you mean? All PRNGs have state right? Which you need to keep secret if you don't want the sequence to be predictable. Is there something more I'm missing?
CSPRNGs keep the state secret so an observer can't tell the next output from the previous ones. Most other PRNGs have a sequence that can be backed out from observing their outputs.
