A map scale allows the map user to figure distance on a map as compared to the real distance. For instance on a map scale 1 inch might equal 500 miles.
A large scale map is a map with much more detail and focus in a particular area. For example, a map of a neighborhood or street compared to a small scale map, a map of Europe.
You would have to refer to the scale markings or legend on the map to determine that. Different maps have different scales.

Yes, bar scales are used to convert map distance to ground distance.
The three map scales are small scale, medium scale, and large scale. Small scale maps cover large areas with less detail, medium scale maps cover regions with more detail, and large scale maps cover smaller areas with the most detail.
Map scales can vary on different maps because they are based on the size and dimensions of the area being depicted. Smaller scales cover larger areas in less detail, while larger scales provide more detail at the expense of coverage. The map scale chosen depends on the purpose of the map and the level of detail required for the specific use case.

Here is a little trick to know how to tell the difference between a large scale map, and a small scale map. A large scale map is a map where your house would look large on it. For example, a map of your neighborhood, or a map of you area. (You can see you house on this map) A small scale map is a map where your house would look small on it (or you can't see it at all), like a map of the world, or a map of Europe. So large scale = large house small scale = small house.
