Idiomatic form

In the first usage it means they failed. The word has many other idiomatic meanings, depending on context. It probably also varies from one country to another.

In the second use of the word, I'm not really sure if it means anything.

By "lottery price" did you mean "lottery prize"?

The sentence does not make much sense. Those who blew what? Where did this sentence come from?

I know that in British English at least to "blow" a sum of money means to spend it all extravagantly in a short space of time.

Here is the sentence where it comes from:

And in May 2007, Stafford won $112 million in California’s Mega ?Millions lottery. And she’s using it wisely. “The ones who blew it also said they were going to blow it,” she says. “They said it before it happened.

Thank you.

That means to spend it quickly, perhaps irresonsponsibly.

Same in American.

Of course, I meant "prize" (sorry, in French, we use the same word "prix" for
The two meanings).

That helps a lot.

But beware of using the word "blow" in other circumstances. Misunderstandings could easily ensue.
