Stocks and shares have been dealt with many times and are not considered as gambling. For example:

A Corporate Lottery?
In view of the risks associated with the stock market, is buying stock the same as gambling? A measure of risk is involved in nearly all financial investments. Some people buy real estate, not knowing if the value of a property will increase or decrease over time. Others deposit their money in a bank, trusting that their savings will be secure. While the stock market is more complicated, simply put, one who invests in stocks buys the shares of a company in the hope that the enterprise will prosper and the stocks will increase in value.
Such an investment differs from gambling because the stockholder has purchased part of a company. These shares may be sold to another person or saved in the hope of future growth. This cannot be said of a person who bets money at a casino or on a game of chance. Against the odds, the gambler seeks to predict an uncertain outcome and win the loser or losers’ stakes.
How much risk should an investor accept? That is up to each individual to decide. Of course, it is not prudent to risk more money on an investment than one is willing to lose.
Hedge funds, futures, options, microcaps, spread trading etc. all carry levels of high risk than traditional company investment and could be considered gambling but I've never heard of anyone being counselled or sanctioned for this type of financial trading.
Equally I don't see this as a green light for the elders to participate in gambling. The WT uses the "wise christians" caveat so I can't imagine many elders would engage in any kind of card game with penny stakes. The odd MS might get away with it but this is basically them trying to stop the elders having to make complex value judgements on those who don't toe the ideal line 100%. It's just the same as the porn thing. If an elder was found to be habitually viewing soft core stuff then he would probably eventually lose his position but the guidence means they can overlook some things, thereby preventing loads of appointed men being thrown off or even more people being DF'ed.
The hypocrisy in this is that there is even some get out mentioned, especially given the points raised by jwfacts.
