I think. It having enough food would be deprivation. But that doesn’t mean you have to have 3 meals a day. And I think you can have a perfectly good home without heating or hot water. These things are nice to have, but are luxuries not necessities I have not had these things most of my adult life
Heating and hot water are not luxuries.
A child who is cold (and never having heating is not solved with layers as easily as the odd night or two) will not sleep as well. They’ll not be as free to play with toys if it’s too chilly so sit and play.
Lack of hot water will mean clothes and bodies being washed in cold water. Clothes, in a house with no heating, will take longer to dry and may be constantly damp. Washing in cold water in a cold house is never going to be conducive to good hygiene.
Even down to simple things - you can’t, as a child, invite your friend round to play if your house is freezing and they can’t wash their hands in hot water after going to the bathroom.
When you can’t invite your friends round that impacts your friendships. The invitations you get lessen. Which then, in turn, makes school less pleasant.
These things may be small individually, but they have a knock on effect. The lack of money or care leads to something else, which leads to something else, and all the small little somethings snowball together into a large impact.
