Laminates, for the most part, are not solid wood as you know it. They can be 1 layer or 2 layers or 3 layers or more in thickness. Some laminates are wood products but when they get wet, they expand and go to mush. The floor may need to be replaced in its entirety, depending on the damage, and may not even be repairable. The type of glue may not be waterproof if this is called into question.
As you've read, if a particular type of flooring is NOT recommended for damp or moist rooms, take the advice on face value. To be quite honest with you, go with tile or vinyl in the bathroom. Happy flooring.
