Anecdotally, yes, but I doubt most users deliberately make themselves unprofitable. There're millions of kids who just want to use voice chat and share meme gifs. Plus Discord has been gating a lot of features behind Nitro in recent years, and they make a lot of money from Nitro/Boost purchases (it's hard to tell since they're privately owned but they might make close to 200 million this year). I suspect they can stay afloat without VC funding (though they keep getting it anyway). And their valuation is really high.
