Yes, it is true.

Are Swedes descent of the Goths who didn't migrated to the south?

Part of them yes, not the majority of them.

The historical core of Sweden is Svealand, the central part of the country, that developed around cities like Stockholm, Sigtuna, and Uppsala. It's seen as the most Swedish part of the nation (see the map). The local tribes used to be called Svears (the Romans in Ancient times called them Sviones = Swedes).

The South (currently called Götaland) used to be populated by the Geats (= Goths) who invaded large areas of Southern Europe, from the Atlantic to the Black Sea. This mass emigration ultimately put them in inferiority in front of the Svears, who became the masters in the Dark Ages.

Caution: the real Vikings were from Denmark and Norway, not from Sweden. Danes and Norwegians undertook epic enterprises in all of Europe, Iceland, Greeland and North America; Ancient Swedes were only interested in Finland and the Baltic provinces (and didn't refrain from grabbing some land to the expense of their Scandinavian neighbours).
