There is a probability that heat will flow from warmer to cooler substances,

and a probability that heat will flow from cooler to warmer substances.

The probability that heat will flow from a cooler to a warmer substance is

so small that it is ignored. It's accepted as a 'law' of thermodynamics that

heat always flows from higher temperature to lower temperature.
