Because of the unequal rates of evaporation and condensation, neither of the glasses in the top part of the figure are in equilibrium.  The two arrows of condensation in Figure A at top tell you there is more water vapor in the air in Figure A than in Fig. B where there is just one arrow of condensation.  The two arrows of evaporation in Fig. B at top tell you the water there is warmer than in Fig. A.

The amounts of water vapor in the two glasses at the top of the figure will change with time and move toward equilibrium.  The equilibrium situations are shown at the bottom of the figure.  The air in Fig. A at the bottom of the figure contains less water vapor than the air in Fig. B.  The air and water in Fig. A at the bottom of the picture are colder than the air and water in Fig. B..
