If I can remember, I have tried crash games once in Rocket pot may be. I had spent near 1mBTC but I was not lucky and crashed my balance. I also think that it is too risky. Anyway, gambling is risky. You can also hit bigger piece of cake in crash game too.
Every game is really risky, it wouldn't be called gambling if there is no risk, however, this crash game could be less risky but it always depends on a certain gambler, if they think they are enjoying it and they can be lucky with this kind of game, then they will think it's not so risky.
The risk is present in any game and I think the higher risk is when you can't control yourself when gambling and you begin to risk money that is already beyond your budge, when doing that, you will be full of regrets when you lose as you might lose your money that you can't afford to lose.
If we can only be responsible, we can enjoy any game even if there is a risk on it.
