Last I checked, buildings don't have a range for gathering.
They did introduce logistics, which might be what you're seeing.
In which case, that is the range for which secondary production buildings in that range will go directly to the gathering camp to pick up supplies instead of going to the warehouse.
It's just that they will prioritize nodes closer to the camp and they will return to the camp to drop off gathered resources.
But no, you can place your gathering camps anywhere on the map and the workers will go to wherever to gather resources.
