It is of course unlikely that someone will spend all their income on fuel.
But the definition of fuel poverty is complicated.
Basically
- Your house / flat has to have an energy band less than C
- They look at what they think it would cost to keep your house warm when it comes to the cost of energy. They then deduct that cost from your equivalised income (See my other thread) and if that amount takes you below the poverty line, then you are in fuel poverty * (this is England's definition)

In 2020, the fuel gap between what was needed to keep a house warm and what people in fuel poverty needed was £223
13% of households were fuel poor.
However, according to the EPC certificates, the median efficiency of houses is Band D - so that means that anyone in a house / flat of Band C or above cannot be defined as being fuel poor - even if they are spending a high proportion of their income on fuel

You can see the energy performance certificate of your house (if it has been done) here

Is there an AIBU? Yes - AIBU to think that is not a very helpful definition as you can be in a well insulated house but still be in poverty because of your fuel bills?
