Oil pressure rises and falls with rpm. An oil pump is rpm based so the faster the engine spins the more pressure it makes usually limited to a certain point. What makes oil pressure lower (new engine as compared to a engine with 200k miles for example) is bearing clearances have opened up from use and causing oil pressure to be lower. If it is much lower there can be a few underlying issues.

Oil pressure also changes with the temperature of the oil. On a cold wintry morning the oil pressure will higher especially at idle until the oil warms up.
