The McLaren driver got tangled up with Bottas as they touched at the tight Turn 1 in Mexico City. Bottas was spun around while Ricciardo broke his front wing and had to pit for repairs.
During the race, Ricciardo said he was kicking himself for feeling that he had caused the incident, but he says watching a video replay afterwards gave him a different view.
"My memory of turn one was that obviously I had a very good start, and it was looking pretty good," said the Australian.
"I went to the inside of [Sergio] Perez and I do remember locking at one point. Replaying it in my head over the next 70 laps, I thought I locked and went up into Valtteri. So I was kind of obviously kicking myself.
"But then looking at the replay, it looked like I locked in the straightline phase and then actually recovered before turning in. And it looked like there was just not enough room.
"Obviously Valtteri came across, probably expecting to have a bit of clear track, and then there was Perez and me. So I don't really blame Valtteri, obviously.
"I'm the one that hit him. But honestly, looking at the replay, I just think it's a first lap incident and a matter of maybe me being optimistic."

The FIA stewards did briefly look at the clash to see if an investigation was warranted but decided that it was simply a racing incident.
Despite the outcome, Ricciardo reckoned that he did the right thing in going for a small gap that was there.
"I feel that it's one of those gaps: if you don't go for it, someone else will and then you're going to get the short end of the straw," he said.
"Obviously I'm disappointed. And I'm still going to be hard on myself and I never want to ruin my race on lap one.
"But let's say, if it's possible to feel any better, I feel slightly better after seeing the replay. And it was actually quite a small hit. But we know these cars don't take much to damage."
