Increasing risk? Honestly I don't get the point, I think you mean increasing the amount of money in gambling? Is it true? 
Stake low means using a small amount of money, I agree this is a good way to avoid severe losses. Sure, there is no way to increase the chance to win in gambling. Even if we use a bigger amount of money, it won't increase the chance to win. It just leads to a bigger chance of losing more money. Some gambler decide to have some limits to ensure using safe money. It includes to limit the amount of money for gambling.

I agree, the goal of gambling is to have fun, not to drain your wallet or stress yourself out all night long because of constant losses due to poor tactics. I believe strategy and control are crucial. Many people, when on a winning streak, often get carried away by emotions and end up losing. Perhaps this is where betting small or large amounts has no value. It's a different story if someone is mentally prepared.
So, in my opinion, perhaps similar to yours, the key isn't just about placing small or large bets, but having management, a playing strategy, understanding who your opponent is, and then consciously quitting at the right time. That's the hard part.
