While you are probably right it's also true that python is just straight up slow - especially in normal configurations (django, flask, uwsgi, lambdas, etc) and elixir is pretty fast while offering a great/fun/friendly dev experience + BEAM-HA/scaling-benefits. They could have also blown everything out of the water with C++ - or probably even golang - but if elixir can do it on 2-4 boxes it's fast enough.
