Doubt Clearance Thread: UPSC 2021

I read that GSLV are used to transfer satellites into GTO only.

However, I had a doubt that Since Chandrayaan and Gaganyaan used GSLV MK3 which are supposed to be LEO (Lower Earth Orbit) Missions, then I mean that isn't it becomes that GSLV can be used for LEO as well and hence it can carry out missions other wise carried out by PSLV as well.

And if it's true, then what exactly remains the difference between PSLV and GSLV. Because, as far as I know, the difference is only due to capacity (PSLV has lower capacity) and PSLV can be used in GTO and LEO missions as well. Now if GSLV can be used for LEO missions as well, then only difference will be due to capacity.

Can someone please clarify, confused a lot when I read about LV used in Chandrayaan and Gaganyaan missions.
