Lightroom Mobile to Desktop

Hello.
i need some help here.

i have bought a  Samsung S9. im taking picture with Lightroom app on it, it takes pictures, take some time (i think syncs or imports) then i can see photos taken

under all images in LR app. (these photos are not visible in Gallary app by samsung).

1. where do LR on Mobile store files? are they synced to Cloud? even that i put it on not sync when on Mobile DATA?

then, im a hobby photographer, so all my works are on LR Classic on PC. with a single master catalog.
i have turned on Lightroom Mobile Sync. and i can see those photos taken with Samsung under Colloction called from LR CC.with edit and rating that i have done on mobile and all stuff. fantastic.

2. how do i save those images to my PCs local drive, so i can remove it from cloud.??

My workflow is im only using Lightroom Mobile/CC to
Select images/rating images or fast editings on the go if needed) so i want those mobile files localy on PC first. then i will do what ever i want.

3. i have moved that LR classic's Mobile Location to "D" drive from basic C drive Photos/LR.......
    after my LR mobile sync is completed on LR Classic. i can see those photos i have taken with Samsung.
But  that folder called   D Drive - Lightroom Mobile -  there are 0 photos. is that because those photos are living on cloud??

Hope you guys can help me out. wasted some time on searching for answer on youtube and google.

Regards,
