If it was a *powered* USB hub then it would probably power the Pico just fine. Obviously a non-powered hub can't do that.
The main thing is to be very careful with your supplies. The best way is to make sure that there can only ever be one supply in place.

it was powered 5v usb hub but they don't send 5v to the connector cable as it would damage a pc. no 5v on the type c connector when powered hub
