No, they are people engaged to be married.
For desi v/s rest of the world (meaning North America and Europe) comparison…
Desi: someone your parents thought is a fine person to be your companion and got you engaged with him
Rest of the World: Someone who was benevolent enough to ‘pop the question’ after a few months of courtship, a few months of living together and a few months of considering if that is the right thing to do.
