Another Noob Fire TV Stick Question Pls - Can I root on latest firmware?

when i purchased my stick the other day I registered and allowed it to update the software.

Am I correct in saying I will not now be able to root the stick :(

if i am wrong about this can someone please give me details on my best options to root and if I do this will I then be able to install the G Play Store?

thanks in advance.
