What is the meaning and origin of the phrase "long shot" ?

AnonymousBut I thought 'a long shot' meant "an attempt or a guess that is not likely to be successful but is worth trying".

As you have seen, 'long shot' can mean more than one thing. Consider a rifleman trying to hit a target a long distance away. That may help you to understand the metaphoric content of the expression.

A related notion is that of an extreme long shot. This can be taken from as much as a quarter of a mile away, and is generally used as a scene-setting, establishing shot. It normally shows an exterior, eg the outside of a building, or a landscape, and is often used to show scenes of thrilling action eg in a war film or disaster movie. There will be very little detail visible in the shot, as it is meant to give a general impression rather than specific information.

Well, that's a definition I found. But what I think about , can a long shot also refer to sport actions , eg a long football shot?
