You can find both function's definitions in file vendor\magento\framework\Data\Form.php.

public function setValues($values)
{
    foreach ($this->_allElements as $element) {
        if (isset($values[$element->getId()])) {
            $element->setValue($values[$element->getId()]);
        } else {
            $element->setValue(null);
        }
    }
    return $this;
}

The setValues($values) function set values according to the array passed in it and set null for the keys which are not set.

Where addValues($values) function does the first part only means it only sets the keys which are available.

public function addValues($values)
{
    if (!is_array($values)) {
        return $this;
    }
    foreach ($values as $elementId => $value) {
        $element = $this->getElement($elementId);
        if ($element) {
            $element->setValue($value);
        }
    }
    return $this;
}
