There are videos on YouTube which are licensed under YouTube license.

And there are many other videos licensed under Creative Commons
Attribution License.

Now, I am sure that the following "terms" of YouTube cannot collide
with the license of the author:

"you agree not to access Content or any reason other than your
personal, non-commercial use solely as intended through and permitted
by the normal functionality of the Service, and solely for
Streaming. "Streaming" means a contemporaneous digital transmission of
the material by YouTube via the Internet to a user operated Internet
enabled device in such a manner that the data is intended for
real-time viewing and not intended to be downloaded (either
permanently or temporarily), copied, stored, or redistributed by the
user."

Sample video is here:

It is unclear to me the exact license version because YouTube claims
on that page that video is basically just for re-use of YouTube users,
but it is not true according to what I know about CC licenses.

Such videos are reusable just by everybody and may be edited or taken
in whatever manner and downloaded.

I am sure that judge in a court would never be on YouTube side when
somebody downloaded CC licensed video, as the rights were granted by
original author and terms of CC license cannot be changed by YouTube.

For that reason is justified to circumvent and avoid the illegal
YouTube terms.
