no reads at all. as the topic states im new to holdem

i guess until the river it is normal to just call down, so reviewing my own hands i thought its a mandatory call here because he could have QJ or 77 combos, but as played he probably never has any sets (except for 77 or sometimes JJ). i dont know if he would 3 barrel KQ like that so i thought i should have QTs in my bluffcatcher range here. but im not sure so i wanted to get some opinions
