Some woman who can actually skate lost a place to him in the competition, and lost a chance to have her talents showcased in the opening ceremony.
Or indeed multiple - being an opening ceremony, they can do whatever they like. They could have had, say, some sort of senior women's skating club or something.
I've not seen the rest of it, but I gather some of the other numbers were same-sex couples, children with Downs syndrome, etc. This one is notable because he's trying to do a solo. That's part of the delusional narcissism - he wants to be the princess in the spotlight.
Note that the "commentator" is actually a recording of him in an interview talking about his skating fantasy - his childhood dreams.
(I did wonder if he was saying childhood injuries, which would have been an excuse, but no. My Finnish is a bit rusty. (Haava = wound, haave = dream)).
He does kind of acknowledge how rubbish he is. It's something like:
"...thought to make true my childhood dreams. To start to sake in women-mode, although I was born a man. And it was nine years, and nine years contained quite a lot. Starting from nothing, to standing on two feet, to standing on one foot, to starting to dare to do something there on the ice. Then to quietly start to compete, to present in shows. [?] It was quite a nice career, then Covid came as a break and messed up the picture, but to go ahead..."
And the interviewer interjects with "These European competitions' slogan is come as you are..."
