It doesn’t. Buying a put option is a bet it will decline because it’s the right to sell a stock at a given price.

It didn't. It went down, crashed pretty hard. I don't think it was the only factor, though.

Zoom would go down, sorry. I was thinking of cruise lines. Pick any one of them and you would profit handsomely. But as others are saying, you can also bet on the stock going down.

I didn't, hence the OP said "put options on Zoom" - that would mean he would make money from Zoom diving (which it did).

It doesn't. It goes down.
