In the Theravada article at Wikipedia, at least they had the decency to put the following factual point:
It is also possible for a lay disciple to become enlightened. As Bhikkhu Bodhi notes, "The Suttas and commentaries do record a few cases of lay disciples attaining the final goal of Nibbana. However, such disciples either attain Arahantship on the brink of death or enter the monastic order soon after their attainment. They do not continue to dwell at home as Arahant householders, for dwelling at home is incompatible with the state of one who has severed all craving."
35. # ^ Bhikkhu Bodhi,In the Buddha's Words, Wisdom Publications 2005; page 376
One may be a householder all the way up to becoming an Arahant, it just that after
that [full] enlightenment is attained, the person will apparently want or need to ordain.
So no need to feel defeated or to not try, there is the opportunity for full enlightenment, even as a lay follower.
