And hundreds of thousands of people in London live closer to City Airport
than to Gatwick, but will still find it quicker to get to Gatwick.

Only if they live adjacent to East Croydon station.

The 22 minutes from Bank seems pretty slow compared to East Croydon to
Gatwick which covers a greater distance in much less time.

The time varies between 15 and 22 minutes according to which train you
get.

But I think you are rather missing the point. London City Airport is
so-called because it operates primarily for people working in the city
and docklands.
