How does each US state have a higher GDP than Most countries in Europe?

Like how is a whole country like France or Germany on par with 1/50 of the US states like it is crazy honestly. I understand that California has a lot of technology and NY is the financial capital of the world but how did all of this happen and why is it like that. It's like the US and China have a $30t economy and Germany Which is no 3 has a $5t economy like crazyyy.

Ik it's a very stupid question but could you please tell me how it works ? Does it have something to do with the USD or just the dominance of the USA
