I definitely think people interpret rural differently. For example, I consider a village to be a few 100 people tops, a town 1000's with multiple shops. Several family members live in the latter with fields 10 minutes drive. They consider it a village. I don't. It's just perspective.
I used to live in a village. Pub, shop, 1 bus a day. Next village 10 minutes drive, town 40 minutes. Technically am probably more rural now as out of a village but 10 minutes drive from town.
1 field does not equal rural living. A lack of gas/mains water/mains drainage often means rural. As do fields for 30+ minutes walk. No public transport or 1 bus per day. No take away including no delivery.
Isolated is something else entirely.
