She's most likely upper-middle class and definitely spent several thousand euros of her (family's) money. But I think you might be overestimating how much she personally spent. Look at all her sponsors (https://flyzolo.com/partners/ https://flyzolo.com/partners/). She didn't go out and buy a Shark at full price of 127k, it was either lent to her by Shark or she got a good discount. All her other sponsors helped out with money or products in exchange for being part of a record setting flight. Some of the copy might sound over the top, but it's way easier to attract help when you're postured as "a young woman with an entrepreneurial spirit on a mission to break down gender barriers, set records, and inspire other young women" instead of "please give me money, I want to go fly."
