Of course, he was incorrect then and is now.
However it is important to note that he didn’t say a minority of women, but “minority opinion” 50% of the population are men, and he’s including them in his comment as well. He then goes on to say he thinks is tiny minority of women who are against.
The fact is the majority of men and women are and have always been against transwomen in women’s facilities.
In addition, even though he said this in 2022 he was still wrong then:

“In the case of allowing such trans women to use women’s toilets, willingness falls from 38% in the generic question to 29%, and in the case of changing rooms, from 34% to 25%.
Belief that transgender men who have not undergone gender reassignment surgery should be allowed to use men’s toilets falls from 42% in the generic question to 32%, and changing rooms from 40% to 28%.”
