Wait, do people at scale use NodeJS and Python for services? I assume always it’s Go, Java, C# etc.

Depends on your definition of "scale", but yes. I ran an app serving ~1k requests/second from a Django monolith around 2017, distributed across ~20 Heroku "dynos". Nowadays a couple bare-metal servers will handle this.
