I have free access to a family member’s camera but it really isn’t the best. I think it has a 1/2" sensor though the sensor is not listed anywhere on the box or in the manual which I guess is a red flag. Should I wait and save up more money to buy a better camera or could I use this one to learn on?
You can absolutely learn on it. Start to get a hood understanding of ISO, shutter speed, and aperture. Practice composing scenes and learning how to edit
