No it doesn't work like that. A vote is either won or lost.
Once again, the way the ERG* voted on May's deal made no difference to the outcome. May's deal was repeatedly defeated by the opposition parties working in alliance with the DUP*. The ERG* votes meant May's deal was defeated by a bigger margin, but a defeat is a defeat, whether by one vote or four hundred. If the entirety of the ERG* had voted for May's deal every time, it would still have been defeated on each occasion.
*ERG = European Research Group (Jacob Rees-Mogg and Co.)
*DUP = Democratic Unionist Party (Northern Irish party, normally supporting the government - but not on May's deal)
