2017~2024 Question on CX-5 Transfer case fluid

:
2019 CX5 Reserve AWD
Does the Transfer case get it's fluid from the transmission? This doesn't sound right but that's what the Mazda dealer Service writer told me.
If that's true then according to them the Transfer case fluid is lifetime.
 
 
Thanks! That proves the Mazda service writer is an idiot.
