Is that an innovation of Mahayana or Vajrayana Buddhism? I've only read Theravada texts, and in those, good and bad Karma are clearly differentiated. Attaining a pleasant rebirth is considered a wholesome pursuit that the teachings of the Buddha are supposed to help you with, though it is considered a lower pursuit than attaining Nirvana (the hierarchy is pleasant current life < pleasant rebirth < Nirvana, and the Dhamma claims to be the supreme authority on all 3).

There are definitely descriptions of virtuous and non-virtuous results of actions (karma) in Mahayana/Vajrayana Buddhism. A teacher of mine, who spent 20+ years as a Gelug monk, gave a nice talk about it from a Vajrayana perspective [1].

The major innovation in Vajrayana would be an addition to the hierarchy you laid out, which is full Buddhahood in this lifetime and the tantric methods to get there. Nirvana/samsara are considered two perspectives of the same reality [2].

I heard any rebirth is samsara, circle of suffering, karma keeps it going, you should clear karma not accrue even more

I don't know the different buddhisms but checked wikipedia about karma in tibetan buddhism and it seems to say it too
