I have an older Samsung tab 3 and was thinking, is it possible to use it as a GPS if I downloaded topo maps?
Im sure Im over thinking this lol

You will need wifi for it to work.
not unless you can download the maps to your sd card in the tablet.
Then it is just a map on a tablet.
OP asked if it could be used as a GPS.
Yes you can use a gps. Go use google maps and they will let you download a select of your map and you could still use gps if its in the area of where your map is downloaded.
I download offline Google maps to various devices. Google time limits the maps for 30 or 40 days. Works great. Your Tab 3 should have no problems with offline maps. Have not used offline topo maps. There are a couple of vendors in the Google Play store.
Offline Google Maps also help your everyday device find and lock on faster with cellphone coverage.
If your tablet has a gps chip, then yes. I use my old Nexus 7 tablet with Gaia topo maps all the time and it works great. Download the maps before hand and you are good to go.
just to be clear, a stock tablet will work for GPS, it will triangulate off the wifi card. if you go off road, there is no wifi. without a local wifi to triangulate to (actually 3 or more), there will be no gps.
a gps chip should get you to within 10 meters, wifi triangulating in a remote area may as much as 65000 meters, but again that relies on a well known fixed wifi spot, the more its reported the better it gets
I would hate to see you going out with a wifi only tablet and get lost
