Yes, the ? and everything after it... with exceptions:

eg:
https://www.youtube.com/watch?v=jNQXAC9IVRw

In the case of above removing this will not work, as it will send users here: https://www.youtube.com/watch (which doesn't get you any video)

In the above case the ?v=jNQXAC9IVRw is saying 'video = jNQXAC9IVRw' which is required to see the video

The goal is to chop down all the extra junk after the ? so that you have the bare minimum that you can paste into a new browser and it gets you to the page you want to share.

url's that have this usually work this way:

https://www.youtube.com/watch?v=jNQXAC9IVRw&t=10&ref=fbid-b3f3f92c-e6fb-4e72-9d6e-9809b7322ae4 https://www.youtube.com/watch - the url
? - the url parameter start
v=jNQXAC9IVRw url parameter 1 (in youtube's case required to see the video)
& url parameter separator (before the next one)
t=10 url parameter 2 (in youtube's case required for the time start index)
& url parameter separator
ref=fbid-b3f3f92c-e6fb-4e72-9d6e-9809b7322ae4 url parameter 3 (in youtube's case this would probably tell youtube facebook ID is responsible for the URL link that they can store and link back to a user when facebook and youtube exchange $ for data etc, and then whoever's id that is is known - that's the kind of thing you want to remove)
