I downloaded a data package of the county of Essex, but how do you find out the metadata of the data package as it isn't posted anywhere clearly, can only see when the data was last updated?

OSM data is vector data, so it doesn't have a concept of "scale" like a printed/rendered map (aka raster data) has. You can can zoom in however much you want.
One thing that can be done with OSM/vector data is to simplify its geometry (to make the file smaller), by removing nodes that won't make a noticeable difference when rendered at a certain scale. But AFAIK the geofabrik files do not do this. And a simplified geometry is still not the same concept as a "1:X scale".
Lastly, the implementation details of how lat/long are stored in OSM mean that we do not have infinite precision. But the limit is smaller than yearly continental drift, so it's not a practical concern.

I'd expect that it would be the same "and contains all OSM data up to 2017-03-16T21:43:02Z" as higher up the page on http://download.geofabrik.de/europe/great-britain/england/essex.html
