Not necessarily, old bean.
I paid nearly ninety sheets for a pair of Merrell ankle boots as they were Gore-Tex and the sole looked sturdy and grippy, and I've regretted it ever since - the soles react like ice-skates on wet rock, wet concrete, wet leaf-litter, wet grass and obviously ice, basically, anything that's wet, is found on the ground and is in West Scotland. The uppers are quite good at keeping the wet out, but that's not really reassuring when the soles are trying to kill me in weather conditions that barely start out as mildly moist.
I only nearly fell on my face twice before I decided to relegate them to dry weather use only and bought myself a pair of Magnum 8.0 Cougars from an online shoppe. They may not be fully waterproof but they grip like velcro gloves on a sheep on ice and all the other stuff l listed earlier.
More than likely the wrong boots for the task. Did you check? If they have mountain soles, they will be designed for deeper mud / substrate and have deeper welts
Most of the big players use Vibram soles (including both Merrell and Hi-Tec) the material is common across most boot manufacturers.
Gore Tex boots are actually tested for grip. They slide the boot across a metal sheet covered in washing up liquid and measure the friction / resistance.
This test is not performed on most non GTX boots.
