"Internet of Things" pretty much by definition requires a connection to the internet, somehow. Technologies like zigbee/thread/etc. can get a device to the internet indirectly via a gateway, but nothing about them is inherently "more" IoT than just connecting to the internet directly. The "Things" part of "IoT" is covered by the Nano ESP32 being a physical "thing", which is able to interface with the real world via the GPIO pins.

Arduino is presumably using the term "IoT" because they're interested in emphasizing that this device can connect to the internet without buying additional hardware, unlike most Arduinos that have existed.
