Is it true that a comet's tail forms when sunlight heats its ice into gas and dust that the solar wind and radiation push away from the Sun?
Yes. Reference and outreach sources state that when a comet nears the Sun, solar heating vaporizes its ices, releasing gas and dust, and that solar wind and radiation pressure push this material into a tail pointing away from the Sun.
