In the very definition of risk, and in every theory surrounding risk management, we find two basic components: probability and impact. Taking measured risks is still a good option for people who prefers to be careful: they will go for low probability and low impact.
And I would say more: even a high probability but a small impact is also a good option for these people, like lotteries and other cheap games with very big jackpots which are almost impossible to win, because even with an extremely high probability of losing, the impact is ridiculously low in personal finances.
In the end, I think that the key is in the balance.
Those who don't like taking risks are unlikely to seek out gambling options, unless influenced by those around them. And if they do end up playing, they will most likely approach it with restraint and discipline, controlling their actions and limiting risks.
