Always possible. However it's been a while since it's been below 450 - so hard to say what the chances are.
 
My CRS Score is 447 ,is there any possibility to get ITA by next draw in May ,2019 ?
Not possible in May or June for sure. And there are chances that they will conduct one PNP Draw and if they will than no chance of CRS TO GO BELOW 449 till July
