Tax consequences for receiving some money as gift ($75000) and sending that over to an educational institution for tuition.

I have been asked to be an NRI sponsor for my cousin back in India. I cant personally fund this amount. So my aunt and uncle will be sending the money (around $75000) from a bank account in Dubai and I will have to send this to an educational institution in India. 

Are there any tax consequences for me if I do this process? As I understand from the IRS website, I can claim upto $100000 as gift. Is there a limitation on who can gift? 

I also read that there are no taxes that I have to pay for tuition (and no limits either). 

Is my understanding correct or is there something I'm missing out? 

Thank you.
