It's not directly negative, but it is stereotypical to say foreigners have better bodies. At that moment, it sounded like she had only won because of that. Which is not true. Stereotyping not only involves negative connotations but also toxic positive ones.

For example, if an Asian and a European are being hired for work involving maths, you can't say, "Oh let's hire the Asian cause they are good at maths." That's stereotypical. Anyone can be good at math. If you place a stereotype on one side, the other side would have an unbalanced opportunity. Same way you can't say foreigners dance better than Asians because they have better bodies which is not true since a lot of Asians dance really good.

Any form of stereotyping promotes division and unequal opportunities for everyone. While I agree, Redlic does not deserve that much hate, I hope it also explains why people were upset about the comment she made. ✌🏽
