The Ab Ghodo Ki Race Mei Gadhe Bhi Daudenge meme originates from the 2007 Bollywood movie Welcome. In the movie, Majnu Bhai (the character played by Anil Kapoor) says this dialogue to Uday Shetty (the character played by Nana Patekar) when Majnu reads the recreated headlines from a newspaper regarding the casting of Uday in a film. The popular use of Ab Ghodo Ki Race Mei Gadhe Bhi Daudenge meme is to mock someone or something for being not up to the mark to compete with others.
