Yes, it's present in all artillery systems, but its effect is more pronounced on self-propelled systems since towed guns tend to enjoy the most stable firing platform, with a low centre of gravity, a rigid gun carriage, and usually the least restriction on recoil distance, which allows them to mitigate the random motion to the best of their abilities.
Tracked systems have a higher centre of gravity, but have a higher contact area with the ground surface as well as greater mass and thus inertia for the random impulse to overcome, in a sense delaying deviation due to the recoil impact.
Wheeled SPH systems have the most challenges to overcome, they tend to have a high centre of gravity, low overall mass, are connected to the ground primarily by a few wheel axes, and each individually would bear more impact and suffer the most deformation, subjecting the platform to tilt or torsion, thus affecting gun alignment. If you remain unconvinced, you should look for some scholarly articles that explain this phenomenon in greater detail.
