tsunade didn't recieve a gift from dan, he only transfered a little amount of chakra to her also you should know that transfering and gifting are two different things also dan gave his chakra to tsunade in order for her to use it as normal chakra, while hag gifted it to naruto and sauke (even in boruto movie and manga was stated that naruto and sasuke have hag's chakra)
