You do seem to ask the same question time and time again
There's a Skoda explanation here https://www.skoda-storyboard.com/en/models/skoda-4x4-your-best-bet-in-the-snow/ which talks about how to drive a Karoq in the snow, and it mentions that "Of course, the throng of electronic stability systems, combined with the Snow driving mode, have got your back and will help to keep the car under control even in fraught situations. On the other hand, if you switch to a sportier mode for wheel spins and bigger skids, you’ll find gliding and watching snow fly in all directions a lot of fun."
It then goes on to say that "Needless to say, 4×4 drive ŠKODAs are not afraid of off-road terrain, even when it’s covered in snow. As with on-road driving, when you’re off-road, fluidity, correctly gauging your speed and sensitive handling are essential. The wheels need to be in constant rotation because if they lock or spin you won’t be able to actively control the car." and "Turning on the Off-road driving mode can be a great help as it allows the car to overcome obstacles that would otherwise be insurmountable. And if you’re unsure what exactly is lying in wait for you ahead, don’t hesitate to get out of the car and walk some of the route on foot – this is still easier than having to shovel your car out if it gets stuck. “If you know what your car is capable of and what its limits are, you’ll be able to enjoy your 4×4 ŠKODA to the full,” explains Stuck."
I've also seen it stated that "Off-Road mode is an extraordinarily complex assistant for more challenging off-road situations. The Off-Road Mode works at a speed up to 18mph, and its function can be divided into three main groups: start and traction support, braking support, and steep downhill support. When it’s activated, all the related assistance systems are switched into a special setting suitable for off-road driving.
It is only suitable for driving on unsurfaced roads, and when switched on, it alters the characteristics of the ESC, ASR, EDL and ABS systems to give improved traction. (ESC helps to stabilise the vehicle by braking an individual wheel, ASR reduces the power to the wheels when they spin, EDL brakes a spinning wheel and transfers power to a different drive wheel, and ABS prevents a wheel locking under braking.)"
While "Snow mode changes how the assistant systems behave so that they help the driver as much as possible on low-adhesion surfaces. The ABS anti-lock braking system, for example, allows for more wheelspin when braking to allow snow to accumulate in front of the tyres to increase the braking effect (the “wedge effect”). In turn, the anti-skid system allows for greater wheel rotation for better grip on winter tyres. The transmission shifts to higher gears at lower speeds than usual, and the accelerator pedal responds more slowly so as to prevent the wheels from jumping into spin with the added torque."
