what exactly is .size()?

An enum in GDScript works just like a constant Dictionary, which means .size() returns the number of elements of State.

By the way, I made some errors in the second line, I corrected them now.

what if i want to choose from certain state but not from all ?

Make an array with the states you want and pick a random element, for example:

var nextState: State = [ State.Idle, State.Walk ].pick_random()
