No. Each force known in physics is thought to be carried by different type of particles collectively called messenger particles. Each type of messenger particle occupy not just a specific number of dimensions, but a specific set of dimensions. So electromagnetic force is carried by photons that occupy precisely the 3 dimensions we see. (interesting huh?, light occupy our three dimensions, hence we see our three dimensions). If gravity occupy our 3 dimensions and then some, those others would be a finite set of specific dimensions, not all other dimensions there might be, nor a random subset of all other dimensions there might be.
So Even if there are a very large number of other dimensions, it would not follow that gravity would therefore be weaker than if there were only a few.
There could be other messenger particles that exists exclusively in dimensions we are currently unequipped to survey.
