Short answer: Historically, yes – Oswal Jains (including Śvetāmbara Tapa-gacch Oswals) are generally considered to be of Kṣatriya origin, but Jain Dharma does not give spiritual importance to varna (caste by birth).

A bit more detail:

• Historical / social view

- The Oswal community traces its beginnings to Rajput Kṣatriyas from Osian (Rajasthan) who accepted Jain Dharma under the guidance of Jain ācāryas. - Because of this, many scholars and community histories describe Oswals as originally Kṣatriya by jāti/varṇa, even though their main occupation later became trade (so in society some people may loosely call them “baniyā / Vaiśya”).

• Jain dhārmik view

- In Jainism, your true status is decided by your karma and conduct (śīl, sādhana), not by birth. - Whether someone is called Kṣatriya, Vaiśya, etc. has no effect on their ability to follow vows, do samayik, pratikraman, tapas, or attain mokṣa.

So, as a Śvetāmbara Tapa-gacch Oswal Jain, you belong to a community that is traditionally of Kṣatriya origin, but in Jain Dharma the real question is not “Which varna am I?” but “How pure are my thoughts, speech and actions?”
