Yes, you're right sort of, but remember the bulkier/harder and the moist/gooey properties can be caused by other things in the food. Thus you do have that yes:
Insoluble is harder, drier and bulkier, and soluble fiber is moister and gooeyer, but you don't have the reverse implication, namely that if something is gooey it is necessarily safe to eat (high SF content). Example: I think mushrooms are a trigger for me, although they are gooey and listed as SF food (I am not sure they are SF, there were topics here saying they were mostly IF)
