At low stakes quick calls are almost always draws. If they had a big hand or a marginal hand, most players would put some thought into raising or folding, deciding whether slowplaying is best, etc. So insta calls on drawy boards are almost always draws.

Similarly, insta-calls of raises preflop tend to be low/mid pocket pairs. A lot of players know they are playing these hands for any standard raise and so call instantly, whereas other hands would require a bit more thought..
