Did people lose all their money with FTX?

Did people really lose all their money with FTX? I'm hearing so much chatter about the collapse of this crypto exchange, but I'm still trying to wrap my head around the whole situation. I mean, isn't crypto supposed to be a safe haven for investors? Or did FTX turn out to be an exception to the rule? I'm just curious to know if people invested heavily in FTX ended up losing everything, or if there's still some hope for recovery. It's a pretty big deal, and I'm just trying to get a clearer picture of what happened.
