More than enough.
Less than enough. Way less than enough. You forget that, unlike a Pole, he has to pay to be in Poland. That means his total travel-related expenses, documents and all other expenses related to the move to and from Poland have to come out of his income. Plus anything he agreed to pay his "agent". That leaves him empty-handed or worse.
Forget savings. He might have to wire his family in India for help to get back home when he realizes he has been scammed.
Anyone offering unskilled work in Poland to people from third world countries is a scam artist. There is zero demand for unskilled labor from outside the EU in Poland that cannot be satisfied by Ukrainians a hundred times over. Chances are exceedingly low that the OP has received a genuine and legal job offer, and even lower that he will ever receive adequate compensation, if any.
