No. There are Japanese people who don't like sushi. There are Koreans who don't like kimchi. (I only mention these things because they are foods I've had before that I really like.) And we can catalog people from all over the world who don't like certain things they are assumed to like because of their cultural identity.
It's bizarre that we have these strong ideals of not stereotyping people and yet these reverse stereotypes are so common. You're not rejecting culture because you have preferences.
But hey if it was just her not liking Durian for some other reason and learning to like it, that's great.
It's just a fruit. King of the fruits, as the poets say, but there are a lot of other fruits in the same tier as well.
But as others said, it's probably partly genetical and habituation. Here in Jakarta durian is almost universal in the proper season, and the smell does not turn off people, on the contrary it signals a savory fruit.
Though I myself don't like durian that much. I'll eat it, but not to the point of obsession. I got rambutan for that haha.
Getting hit by a flying durian and die is a not that uncommon way of death though. At least in the pop culture.
I absolutely love durian and I rue the fact that it is hard to find (and expensive) in Central Europe. I find the odor strong, but not repulsive.
My wife, OTOH, hates it with passion. She cannot eat it even outdoors, where the wind blows the smell away.
Or does she use the word in place of just "Chinese"?
Mandarian is a unique dialect of Chinese. Singaporeans also speak other dialects of Chinese in Singapore but Mandarin is one of the official languages of Singapore so it's what is taught in schools.
You can find elements of Hokkien, Hakka and Cantonese dialects mixed into typical Singaporean Mandarin. These have been frowned upon by academics and the government (Singlish has also been frowned upon and incorporates them also) but that hasn't changed the use of these.

Taiwan has similar dialects: there is Taiwan Mandarin as well as Taiwanese and Taiwan English.
Fun Fact: Singapore and mainland China use simplified Chinese characters. Taiwan and Hong Kong use traditional Chinese characters.
Suffice it to say it seems to be a false friend of the Cantonese pronunciation of the word 熱 which is pronounced "yeet" (rè in Mandarin)
English (official) 48.3%, Mandarin (official) 29.9%, other Chinese dialects (includes Hokkien, Cantonese, Teochew, Hakka) 8.7%, Malay (official) 9.2%, Tamil (official) 2.5%, other 1.4%; note - data represent language most frequently spoken at home (2020 est.)
