I feel like I'm not a very good devotee and don't have the right background. Does Chapter 30 offer any reassurance for people like me?

Yes, Chapter 30 provides significant reassurance for devotees who feel they are lacking in spiritual qualifications. The author contrasts learned Brahmins performing rituals with those who feel they are 'devoid of proper samskaras and of little power.' The most powerful and comforting message in this chapter is the direct statement: 'Even if everyone abandons us, Sai does not forsake us.' This highlights that Sai's grace is not contingent on one's knowledge, lineage, or ritualistic purity. According to Chapter 30, upon whomever Sai bestows His grace, that person attains great power and the knowledge to discriminate between Self and non-Self, demonstrating his unconditional support for all his followers.
