What is the differens between watts and votts?

Volts are a measure of electrical pressure....... symbol V Watts are a measure of Electrical Power.....symbol W Now interestingly Watts are a product (or is it sum, I can never remember) of the Volts multiplied by the Amps (symbol I) written as W= VxI ie 20Watts = 10Volts x 2 Amps. Transposing the formula above gives the relationships between Amps, Volts,Watts. Resistance is also a player.......... symbol R (unit is Ohms) but that's not the question Hope this helps.

Why transformer rated kva?

The correct symbol for kilovolt amperes is 'kV.A, not kva. A volt ampere is the product of the transformer's secondary rated voltage and its rated current. It is not rated in watts, because the transformer designer has no idea what sort of load is to be applied to the transformer, and it is the load that determines the amount of watts, not the transformer.
