Shortly
now there was 3½ million Finns against 180millions Soviet citizens, at the end of war SU had concentrate some 5000 tanks against the Finns, 2-3000 a/c etc. There were no chance that Finns could have pushed Red Army back to border in the main combat zone, SE Finland. Finns had some 15 tanks some 150 A/T guns and maybe 125 combat aircraft. The numbers are from top of my head, I didn't bother to check them, but Soviet numbers should be appr OK and Finnish equipment inside +-20 pieces.
Germans kept eye on the things, firstly, they were worried that British would cut the very important iron ore import from Northern Sweden to Germany using help to Finland as excuse. Also made conclusions on the combat capacity of the Red Army, and they didn't realize that Soviets also draw conclusions and began to improve their army.
