If you put all the black holes of the universe on one side of an imaginary scale and all the rest of the universe on the other side, then which side has more mass?

The non blackhole side. There are several hundred billion stars in a galaxy, the lightest of which have a mass of around 1/10th of our Sun, overall the total mass of our galaxy is nearly a trillion times the mass of our Sun. In comparison, the supermassive blackhole at the center of our galaxy weighs only around 4 million times that of our Sun. The smaller blackholes around the galaxy don't significantly affect the balance of mass much. The same overwhelming ratios of mass hold for other galaxies as well.
