Why do models have the effect of pixel edges when imported into unity and how to fix it?

Question

Unity

When I import the model into unity its edges look like pixels. Is there a way to fix this? For example, in Crossy Road, the edges of the shapes look normal. Does it somehow depend on the position of the camera? Or how does it even work
