Random unsolicited internet advice: never decide not to apply because you don't feel good enough. We all experience imposter syndrome, and most job postings are just wishlists of unrealistic qualifications copy-pasted by HR anyway (this posting excepted!).
In general, don't disqualify yourself. That's the hiring manager's job. Your job is to qualify yourself: present your best self, and demonstrate professional confidence and competence.
