Amaranthus seedlings help?

So I impulsively decided to try growing love lies bleeding and honestly I figured I wouldn't be successful getting any seeds to sprout; so I ended up putting two to three seeds in each pot. Will I be able to separate them once they get a little bigger? Or have I doomed myself from the start?
