Why cant liquid water at 273.3 k will not freeze in terms of gibbs energy?

Water cannot freeze at 273.3 k in terms of gibbs energy because when absolute zero (Which is 273.3 k or 0 celcius) is achieved than the water will be at equilibrium, which means that the water melts at the exact same rate the water freezes.

Absolute zero has not been achieved, so there is no example of this.
