Yes, it does. As I said in response to you elsewhere, insurance means not accepting huge variance in payoff, whereas gambling means you do accept it. They're opposites of each other. The fact that the counterparties in both cases--insurance companies and casinos--end up making money from all of their customers on net does not mean the two things are the same.
IMO the main difference is that insurance provides two good outcomes while gambling only one.
So you're buying car insurance. There are two outcomes: either your car will survive another year or you'll crash. First outcome: you're happy because you've got a survived car. Second outcome: you're happy because you've got insurance payout.
Now you're buying lottery ticket. First outcome: you won the lottery and you've got the prize. Second outcome: you didn't win the lottery and you lost your money spent on lottery ticket.
I believe I said that insurance is gambling, not that all gambling is insurance. If not I apologize. So I should be covered by what I already said elsewhere, that buying insurance is betting (aka gambling) that a bad thing will happen sooner rather than later or never.
Now is all gambling insurance? Hmm. Maybe betting that something will happen is equivalent to insuring against its happening not financially benefiting you. Boom.
Mostly I agree. That doesn't make it not gambling though.
