You are right, gamblers are risk taker and maximum time gamblers are loser only few gambler on few time can make profit I mean they can win but maximum time they will loss.
Let's me paraphrase your ideas a little bit clearer and easier to understand.
In short term, gamblers can win, or big win, but in the long term, they will lose, big lose.
In short term, gamblers can beat casinos, but in the long term, casinos will beat them entirely.
Let me also take a stab here, since we're all doing each other a favor;)
Gamblers are big risk takers, by nature of the definition of the word gamble, it is a play on chance and luck.
Because the nature of the risk takers is that they will gamble to lose something, in the hope of winning something even bigger, they eventually lose, because the ultimate win is never big enough. But me, I'm a fun gambler. I seek enjoyment and I know I will lose my deposits. If I win, it's a bonus, but either way, I do it to have fun. If you cannot see that losing is the most likely outcome in the end, then you don't understand how casinos work:)
