As stated above, yes you are right. It is a zero ohm resistor - for all practical purposes. We can get all technical and say it isn't exactly zero because it's not a superconductor, but it's as close to zero as a piece of wire.
As well as jumpers, they can be used for configuration setting on a board or sometimes you might have a circuit that can have (something like) a current sense resistor in place for testing, but will work better with zero ohms in a production run.
For SMD boards, a zero ohm resistor can be positioned with a pick and place machine just like any other SMD component.
