I just want to know if I processing this correctly... On the river if I believe that I have more than a 25% chance to win the pot I should call?

you're betting 28c to win 80c, so your percentages are about right

In terms of pot odds, yes, you're getting about 3.85 to 1 or 26%.
I wish you hadn't posted the spoiler, because based on the action it looks a lot like a bluff with a missed straight draw on the river. At these stakes it's rare to see someone checking trips on a blank turn, but I guess the guy decided to slowplay, so he's trying to get value on the river.
