Can airdrop be converted to money?

Could you please clarify for me whether airdrops can actually be converted into cash? I've been hearing a lot about this concept lately and I'm quite curious to know if it's a viable way to generate income from cryptocurrency. Could you explain how the conversion process works, if it's even possible? Also, are there any specific conditions or requirements that need to be met before an airdrop can be converted to money? I'd really appreciate your insights on this matter.
