B.G 4.09
जन्म कर्म च मे दिव्यमेवं यो वेत्ति तत्त्वतः। त्यक्त्वा देहं पुनर्जन्म नैति मामेति सोऽर्जुन ॥९॥
janma karma ca mē divyamēvaṁ yō vētti tattvataḥ। tyaktvā dēhaṁ punarjanma naiti māmēti sō'rjuna ॥9॥
O Arjuna, One who understands My birth and actions as divine governed by the principles, is not born again, after renouncing the body, as he attains Me.
Gīta Tātparya 4.09
Mere birth and actions don't give liberation. It is the integration of the knowledge of all qualities mentioned in Vedas and Epics that results in liberation.
"It is emphasized in different places. The liberation is possible always only by the integration of the knowledge of the qualities that are mentioned in Vedas and Epics, by control over senses, devotion, and such activities; not in any other way."
-such is the proverb from Brahma Vaivarta Purana.
The phrase 'Janma karma cha' does not mean merely by birth, action, and such activities one obtains liberation.
