Can I use USB type c on my iPad 10.2?

Yes - you can connect USB-C devices to the Lightning Port of your iPad by using the correct adapter and cable. So as to connect any USB device to your iPad, you will require an Apple Lightning to USB 3 Camera Adapter:

If connecting external USB devices, you’ll need to consider that the iPad is unlikely to be able to supply sufficient power to the external device - and without adequate power the external device won’t work. One way to resolve this to connect a Power Adapter (charger), of at least 12W capacity, to the Lightning connector of the Camera Adapter.

The external device will also require an appropriate cable to connect to the USB port of the Camera Adapter. A cable that supports USB 3.1 is recommended.

No it has a lightning connector on it.

Nope.

A 2019, 10.2 inch screen iPad uses Apple's proprietary Lightning connector port.

There is NO USB-C connection on this iPad nor on the 2019 iPad Air 3 nor the 2019 iPad Mini 5.

Sorry.
