There is one confusion that in kirchoff's second rule the statement is that the sum of all the voltage changes is equal to zero but there is no sum function in its equation as well as in wheat stone bridge. So how could it be called as sum of voltage changes? It is the difference of voltage changes🤔

Variables means "changing" not unknown. So the resistance of variable resistor could be changed but we know the changed value. The unknown resistance is the one which is to be determined.
