but just to confirm is he right?
Yep, it's EU subsidised and for EU citizens (plus a few others that have quite close links to the EU) only.
if he is how is it that turkish blokes come here and study(i have some in my uni)?
They're quite closely linked with the EU in some respects and there are bilateral treaties governing this sort of thing. Turkey will probably never become an EU member, but they do cooperate in many, many ways. The Customs Union is one example.
what else can i do to get student exchange to another country without actually shelling out a ton?
Check your university in Poland, check universities elsewhere to see what scholarships are available - if you're an exceptional student in Poland, you might find doors opening up for you.
