Answer

Yes. In Jain tradition, Bhagwan Rishabhdev is regarded as the first Tirthankar and also as the originator of organized human society. He is remembered as the one who taught people the basic ways of civilized life, including the six arts and occupations. His lineage is associated with the Ikshvaku vansh. ( jainqq.org)

Explanation

So your point is broadly correct: Rishabhdev is not just seen as a spiritual teacher, but also as the first great organizer of social life in this era. Jain texts and traditional Jain writings describe him as the one who helped establish proper conduct, work, and social order after the simpler early age. ( jainqq.org)

About Rama, Jain tradition also places him in the same Ikshvaku/Suryavanshi royal line. So the idea is that Rishabhdev comes at the beginning of that sacred lineage, and Rama appears much later within it. ( jayasreesaranathan.blogspot.com)

Spiritual Understanding

In Jain Dharma, this is important because it shows that Rishabhdev was not only the first Tirthankar, but also a giver of civilization, discipline, and dharma in human society. His role is seen as foundational both spiritually and socially. ( jainqq.org)

Takeaway

Your understanding is close to the Jain tradition: Rishabhdev is considered the beginning of organized society, and Rama belongs to the later Ikshvaku lineage. If you want, I can also explain this in a simple timeline format.
