Should I call or fold with so many outs on the River?

So in this hand I had 9 Club outs, 4 9 outs and 4 Aces outs for a total of 15 outs on the river (since I cant count the 9 and A twice). Was it the right play for me to fold after the Turn based on the bet size of my opponent?

I have to type this out on hand since I am using a site called Global Poker here in the United States

The limit is .02/.04
4 People at the table

SB Stack Size 25.5BB
BB Stack Size 71.75BB
MP Stack Size 118.50BB
Hero (BU) Stack Size 108BB

Preflop Hero is Dealt
T♣: Q♣:

MP Calls 1BB
CO Calls 1BB

HERO (BU) Folds

The reason I folded here was because the pot was only 16 BB before his bet of 20.5 BB which seemed really suspect. He was a loose player and also had a short stack and this basically put himself all in. He definitely had a hand, and my concern was chasing on the river, even though I had so many outs which is why I folded. Also even if I hit the river, he had no more money so I felt like it wasn't a profitable call. I was really hoping to see my straight or flush on the turn.

Did I make the right play?

Thanks in advance.
