Online gambling Law

Sir my question is by law TDS stands for Tax Deduction at Source, under section 194B of the Income Tax Act, winnings from lotteries and games have a corresponding TDS of 30% provided the amount is at least Rs. 10,000. In poker, aside from TDS of 30%, an additional 0.9% is included as Education cess tax

if a online gambling site deduct Tds on 100 rupee 30% is it legal
