Exactly. I think it is great for people like you to inject some more realistic expectations into discussions like these.
An entity like Amazon is not - in the longer term - going to escape fate, but they have more budget and (usually) much better internal practices which rule out the kind of thing that would bring down a lesser org. But in the end it is all about the budget, as long as Amazon's budget is significantly larger than the attackers they will probably manage to stay ahead. But if they ever get complacent or start economizing on security then the odds change very rapidly. Your very realistic stance is one of the reasons it hasn't happened yet, you are acutely aware you are in spite of all of your efforts still at risk.
Blast radius reduction by removing data you no longer need (and that includes the marketing department, who more often than not are the real culprit) is a good first step towards more realistic expectations for any org.
