While the great lakes were formed by glaciers they're currently refilled more by rain/snowmelt than glacial meltwater. Rivers flow in, lakes get fuller, rivers flow out lake gets lower. And ofc, rain and evaporation on the lakes themselves make a difference too.
As for why they haven't evaporated, they're fucking huge man. Really fucking huge. Even if they were losing more water than they take in (they might be, I don't know) it'd take a long long time for them to disappear or notably shrink.
