Answer

No, I would not call that a standard, universally accepted Digambar Jain scriptural fact.

Explanation

In Jain tradition, stories about souls going to Devlok are possible, but such a birth is based on karma, punya, and inner state of the soul, not simply because a snake cut them.

So if the story says:

• two girls were cut by a snake, and
• then they went to Devlok,

then this is best understood as a local katha or devotional story, not as a core, confirmed Jain siddhānta unless it comes from a specific recognized text.

Spiritual Understanding

Jain Dharma teaches that:

• moksha comes through right faith, right knowledge, and right conduct,
• deva gati is still within संसार, not liberation,
• and death by itself does not decide the next birth.

So such a story should not be treated as a general rule of Jainism.

Takeaway

It may be a traditional story, but it is not something I would state as proven Digambar Jain doctrine. In Jainism, the soul’s next birth depends on karma, not on the method of death alone.
