I'd say it's less about the number in the bank account and more about the perceived safety you feel. Similar to the lower two layers of Maslow's Hierarchy of Needs. If you don't think that the worst outcome of pursuing something you truly love is manageable, you're less likely to put yourself up to that risk.

In US this might correlate more strongly to the numbers of zeros in the bank account or the salary difference to similar workers at FAANG. But feeling of safety is subjective and depend a lot on the environment you're in so I don't think that's universally the case.
