Not true. Our standards define poverty either as the inability to afford lower-tier living expenses, or as the inability to ensure an income higher than a certain quantille of the population's income distribution (typically around 60% of the median income )

Both interpretations of poverty imply that none of your hypothetical examples represent poverty.
