That's a clear overstatement for which I can't find any evidence.
Contracting HIV with unprotected sex is difficult (1/1000 for vaginal sex and insertive anal sex, 1/71 for receiving anal sex - all numbers for unprotected sex) [1], breaking a condom is also difficult (4% cases in anal sex between gay men - which is the higher number [2]). Meaning that contracting HIV while wearing a condom, is extremely difficult (0.05% in the worst hypothesis).
It's up to you then, to prove that PrEP is more efficient than 99.95% of times (while still disregarding that unlike condoms, PrEP doesn't protect you in any way from other STDs... yes, those STDs that people not using condoms and that think they are entitled to have other tax/insurance payers providing PrEP for them, are spreading around).
