Hello Teddy - welcome.
Virtually the whole of Revelation is - according to the JW's - "symbolic". And yet the 144,000 of Revelation CH 7 and Ch 14 is supposedly "literal" even though it is made up of 12 x 12,000 from symbolic tribes of Israel.
Without wishing to be disrespectful the opinion of this poster (who was baptised as a JW 40 years ago and who was dumb enough to be an elder for over 20 of those years until I realised it was a croc) is that it is "all bollocks."
I would further encourage you to "run Forrest run" as far away as you can from this self serving little cult.
