Does the odometer revert back to 0 at 100,000 miles ?

No it doesn’t

Not counting tenths…
On an older 5 digit odometer yes, on the newer ones (for decades now) 6 digit odometers no they do not, you would have to hit 1,000,000 miles for it to start all over, unless there is a malfunction of some kind…
