ELI5: How can geologists really know that there is a miniscule chance that the Yellowstone super volcano will erupt in the next few thousand years?

To explode the rock under the ground needs to be more lava. Currently all of the rock is actually rock. We would begin to see more activity and magma prior to an explosion. This change would take a long time. Therefore we know it’s not happening anytime soon.
