I feel like you're trying to reach for some sort of 'gotcha' here, but there isn't one. The parent comment's point is that people should be aware of when they've gotten lucky and be able to engage with the world when that luck finally runs out (or, at least, engage with politics that can realistically preserve some of that luck).
We've all won considerable lotteries just in being alive. One out of 100 million sperm, avoiding perinatal death, a nurturing family, household, community, country, "choosing the right parents", a locally advantageous ethnic or tribal status, well-functioning social institutions (especially healthcare, education, general safety, law and justice, sanitation and infrastructure, environmental protections, clean water, safe food0, an encouraging relative, neighbour, teacher, mentor, or boss (vs. the opposite), a healthy or growing economy, personal talent, temperament, or skill, happening to get interested in a hot topic or subject, access to labour markets, access to entrepreneurial markets, suportive labour, professional, or entrepreneurial institutions, a social safety net, physical appearance, mental health.
These and many other factors have a high element of luck. Absence of any one can prove a tremendous (though not necessarily unsurmountable) handicap.
But, and this is key: dashed expectations, even where born of a lottery, can become huge personal and societal problems. The stages and processes of grief: denial, bargaining, anger, depression, acceptence, are born from a dramatic shear in expectations.[1] (Differences across social groups, as in racism, are a related phenomenon, though different in that it is distenctions among- rather than within-groups but over time, that are involved.) Writ large over society such disapointments can be exceedingly potent forces, particularly politically.
Discover your own lottery card(s) overpromised and underdelivered, you'll likely feel similarly.
The exectations set up through cultural mythos can prove to have a tremendous downside debt of ther own; "rugged individualsm", "self-sufficiency", "meritocracy", "American dream", "technological progress", "free markets", "manifest destiny", "self-made (wo)man", etc. All of these have fascinating, if not widely known, ideological foundations. And historical literature on each often shown sharp, if buried, contemporary criticism.
