Okay,
The first (1.34) clip is from the September 5, 2015 National Book Fair interview in Washington DC
Here is the full session with the little girl, Zoey in context:

Here is the relevant exchange:
Zoey
- Why has nobody been to the moon in such a long time?
Aldrin
- Ha...That's not an eight-year-old's question; that's my question; I
want to know, but I think I know. (pause) Because we didn't (pause)
go there and that's the way it happened and, and if it didn't happen,
it's nice to know why it didn't happen so in the future if we want to
keep doing something we need to know why something stopped in the
past that we wanted to keep going. Uh....money..is a good thing. If
you want to buy new things, new rockets instead of doing the same
thing over, it's going to cost more money and other things need more
money too. So having achieved what the President wanted us to do and
then what thousands, millions of people in America and millions of
people around the world...You know when we toured around the world
after we came back...the most fascinating observation were signs that
said, "We did it" --not just use, not just America, but we,
the world, different countries. They felt like they were part of what
we were able to do and that made us feel very good.

I think its abundantly obvious in context that Aldrin is talking about the period following the Apollo program. NASA went off in an entirely different direction (A reusable Space Shuttle)
There's a hulluva difference between saying we didn't go back to the moon because we didn't and that's just the way it is versus saying we never went there at all and it was all a hoax.
The latter can't be squared with Aldrin's mention of the money a new moon program would cost or his emotional recollection of the We Did It! signs (Which actually were a thing) or his statement that we achieved what the President wanted us to do or his response to other questions in the interview. (e.g. Weren't you a little scared going to the moon?)
I'd also add that you are citing Flat Earth sources. I'm hoping you haven't gone down that rabbit hole too.
