No its a discussion about the words losers and winners in terms of electoral success. Johnson was very successful in winning an election, whether I agree with him is irrelevant to that.
On the other point, I think it's possible Reform may become an electoral force, small parties tend to be vulnerable to infighting but if they can avoid that its possible. The Tories tend to behave quite bizarrely after an election defeat, so there will probably be a few wilderness years! There are a group of people not represented by any party at the moment, they may head to reform, particularly if there is a charismatic leader there.
