I'm not a lawyer.. but I can say two things.
1. I agree it's unfair, and it seems ridiculous from ittf's side to claim copyright on material just because it's "their tournament" when the video is not taped by them, they shouldn't really have the right to do that.
but 2. Do they have the right? What does the law say? (idk tbh) That's sadly the only thing that matters until you can claim their copyright strikes false.
I also found it funny (or stupid :v) that ittf called copyright on Xu Xin's best point in the Chinese superleague.... as that's not really ittf, but cttsl.. like, I had ittf related points, but they choose to copyright the one that was from a Chinese channel, under cttsl... but I didn't really care for that since I was already using copyrighted tunes on the video that I didn't want to change xD
Edit:
Did some "Light" digging, came across this (which I assume will be the same for "ittf" in their tournaments)

So you have two ways to gain the right (without copyright infringement)
1. You get an agreement with them
or
2. You research "fair use" and edit the vids accordingly... always keeping "copyright material" short and with edits or commentary. Although fair use is easier said than done juridically.
