Will we all attain enlightenment eventually?

Since the Buddha said everything is impermanent (*anicca*) '*yan kinci samudaya dhammam sabban tam nirodha dhammam*' and ignorance (*avijja*) is something, won't it be the case that ignorance (*avijja*) will cease for everyone (ordinary folk (*puthujanas*) and those-in-training (*sekhas*) alike) eventually? The Buddha did say that ignorance (*avijja*) is impermanent (*anicca*) actually. >*jarāmaraṇaṃ, bhikkhave, aniccaṃ saṅkhataṃ paṭiccasamuppannaṃ khayadhammaṃ vayadhammaṃ virāgadhammaṃ nirodhadhammaṃ. jāti, bhikkhave, aniccā saṅkhatā paṭiccasamuppannā khayadhammā vayadhammā virāgadhammā nirodhadhammā. bhavo, bhikkhave, anicco saṅkhato paṭiccasamuppanno khayadhammo vayadhammo virāgadhammo nirodhadhammo. upādānaṃ bhikkhave…pe…. taṇhā, bhikkhave… vedanā, bhikkhave… phasso, bhikkhave… saḷāyatanaṃ, bhikkhave… nāmarūpaṃ, bhikkhave… viññāṇaṃ , bhikkhave… saṅkhārā, bhikkhave… avijjā, bhikkhave, aniccā saṅkhatā paṭiccasamuppannā khayadhammā vayadhammā virāgadhammā nirodhadhammā.* > >Ageing-&-death, bhikkhus, is impermanent, determined, dependently arisen, its nature is to be destroyed, to disappear, to fade away, to cease.
