The Wales manager was realistic but defiant after seeing his team outclassed by Belgium who left the Cardiff City Stadium with a controversial 4-2 victory.
The controversy came with a hugely disputed penalty awarded for handball against Ethan Ampadu that handed the Belgians a lifeline when they trailed 1-0.
But Belgium had more than enough ability - especially from the brilliant Jeremy Doku - to repeat the victory they earned against Wales in Brussels.
“It’s unlikely, I agree,” said Bellamy when asked if Wales had any realistic hopes of progress through their qualification group - or if they would need to finish second for a play-off spot or else use their play-off place earned via the Nations League.
“We wanted top spot because then we go straight through - we go straight to our goal.
“But I'm aware of where we are as well. I'm aware of what the Nation's League for us.
“I'm aware, also, if we finish second as well in this group, you know, this, you know, there's another opportunity to be able to get to this major tournament.”
Wales are all but certain to be in the play-offs in March - either by finishing second or third. They will have home advantage for the play-off semi-final if they finish second in their group.
If they are third, they would have an away semi-final play-off thanks to their Nations League record.
It might have been a different story had German referee Daniel Siebert not decided to award a penalty when the ball struck Ampadu’s arm in the 18th minute after Joe Rodon had given Wales a deserved lead.
The ball struck the Leeds United player from close range and Bellamy felt it was the kind of call referees now no longer make in the Premier League.
“We've got more common sense, but I have watched plenty of Champions League football games to know what can happen.
“I don't know where you're supposed to put your hands, but if it goes anywhere near your hands, then it's straight away a penalty, which I don't believe is the way the game should be.
“Now, that's not sour grapes - far from it.
“I'm completely aware of the capabilities of this Belgian team, of course, but I just felt that it interrupted the momentum that we were having.
“And the fast start and the crowd, you just sensed it was like a sucker punch to everyone - the players, myself, the crowd as well.”
The gulf between the teams was clear, however, a fact Bellamy conceded when he pointed out that Wales scored five goals against them in the two contests but did not earn a single point.
Either way, Bellamy insisted he will not change his attack-minded, possession-based strategy - whatever the outcome of the likely play-off route when it comes to reaching the USA, Canada and Mexico next summer.
“I told you at the start when I was going to do this, there will be no sitting back. I know that goes against some of the people, but this is who I am.
“And today I've seen a team that wants to do something, because I want to as well. I have to compliment the players on that. And I'm grateful for that.”
