That is true provided that you have devices that correctly act as routers. Sometimes it requires extra repeaters to make the network function correctly as well. Then there is the interference issue from WIFI and Bluetooth devices.
You can even visualise the network if you're using zigbee2mqtt with zigbee2mqtt/bridge/networkmap
