a rich man's gambling casino

Dear all,

can you help me paraphrase the line "the market is like a rich man's gambling casino"...I've found this line in articles (for exapmle "Wall Street is just a rich man's gambling casino"), but I can't seem to grasp the meaning and paraphrase it in an adequate way...

Thanks!

Welcome to Using English.

The stock market is where rich man can gamble.

Do you understand what it means to gamble? They place bets. If you don't understand the stock market at all, then this won't make sense to you.
