The problem with that show is it is all simulated. They have a camera crew following them round so they cant exactly hide properly.

The show is set up so that if the contestants do anything on a given list (like access ATMs, pay for something with a known card, walking past cctv cameras etc) then the camera crew would notify the hunters. Thats how they got that intel so that they wouldnt need to use actual methods.

I dont think you can use that show as an actual example of somebody on the run. Its so far away from reality and set up to be interesting to the viewer, its just not realistic at all.

Hunted is a different case tho, there they know the person's identity and need to find there location (and direction).

In the parent case the supposed illegal activity is associated with a device (possibly the location) and they are trying to find the identity of the person associated.

A good reason to keep a moderate amount of cash hidden on hand. Not so much that losing it would ruin you, but enough that you wouldn’t need to visit an ATM if you actually needed to hide for some reason.
