Some Questions Regarding Watermark Prediction

I have a technical question regarding watermark extraction: 

If I use Watermark Anything (WAM) to embed a watermark into an image, can others use a watermark prediction model to locate and decode my watermark? 

If there is such a risk, how can I ensure the security of the watermark and prevent it from being predicted and decoded by others?

Looking forward to your reply. Thank you very much!
