“German Economy Minister Robert Habeck said Germany has a chance of getting through the winter “comfortably” despite the lack of Russian gas. Germany is on track to meet a 95% storage capacity target by November.”

It is less likely however, that Russia will get through the Winter, or the next many years comfortably, without the revenue from those former gas sales.
Europe has signed long term supply contracts with other producers - 10 and 20 year contracts.
China will tell Russia what it will get for the remnants of Gazprom, and beggar Russia will have to take whatever its new overlord deigns to provide.
Putin did that.
