The income tax deducted on lottery winnings cannot be claimed as a refund as it is the straight income tax deducted from the winnings of the assessee
The person paying the prize money, which is usually the organiser of the lottery, crossword puzzle, game shows, dance competitions, etc., is liable to deduct TDS under Section 194B
Usually, taxpayers can claim a refund if the TDS deduction is more than their tax liability in an assessment year. That said, for lottery winnings, you cannot claim any refund.
