No.

In Digambara Jainism, confession and sincere repentance alone do not guarantee heaven. Heavenly birth depends on the overall balance of punya and papa karmas, along with right conduct, restraint, and purity of mind.

So, if a person has committed many sins repeatedly in the past, proper confession can reduce the bondage of karmas, but it is not a direct ticket to heaven.

For a female layperson, the same karmic rule applies: heaven is possible only if the accumulated punya is strong enough, not just because of confession.

So the strict answer is: No, not निश्चितly / not by confession alone.
