Am i stupid or it was a scam ?

while i was playing payload someone from my team wanted to trade for my 3 different war paint in exchange of anything from his inventory thats where i got SUS because he had lots of items and +1000 trade exchange etc. looks legit kind of but i asked why cant you just buy from the market he said i dont have money in steam right now all 3 paint cost 1.30 dollar more or less he didnt send any link etc. but i declined anyway is there any way he can scam me tho if i just accepted trade via steam
