Can airdrop make you rich?

Could you please elaborate on the question, "Can airdrop make you rich?" I'm curious to understand the potential benefits and risks associated with this cryptocurrency phenomenon. Could airdrops really lead to significant financial gains? Or are they more of a marketing gimmick with limited upside? Additionally, how do you evaluate the legitimacy and sustainability of airdrop projects? Are there any specific factors I should consider before participating in an airdrop? Thank you for your insights.
