Yes. There’s the Central Government Act(The Public Gambling Act, 1867).This act comprises on 18 Sections. In Section 12 (Act not to apply to certain games), it clearly states that – “Nothing in the provisions of this Act contained shall be held to apply to any game of mere skill wherever played.” That means fantasy sports that are part of skill-based games are excluded.
