I haven't watched this particular video, but it's worth pointing out that the channel (Kurzgesagt) is funded by the Bill & Melinda Gates Foundation (and possibly some part of the German government, IIRC, but I can't find a source for it right now), so be wary of any political content like their video on climate change
Kurzgesagt gets funding from the German public broadcasters ARD and ZDF. Their financing model is a little weird but they are in practice state media. German liberals love to claim that they're not state media as their money doesn't come from the government but a separate household broadcasting fee.
In looking that up I found mostly German media articles referencing the partnership (it looks like it's primarily to support the production of German language content). There's also a bunch of far-right German libertarian type conspiracy blogs raving about how these videos are all lies.
