Yes, but you get on with the business of having the drink and don't let them melt.
Ice from the freezer is about -18C (depending on the setting), you put it in a drink and it will draw the heat from the liquid to raise the temperature of the ice. Then, it needs a shit load of heat energy to turn the 0°C ice to 0°C water.
