The definition of rich in my opinion is also quite random, in fact, quite a lot of people say that the definition of rich according to them is a healthy body/mental and a complete family, currently, i live a quite comfortable life, the business i have built is also quite stable, my family is also very harmonious then it can be said that for now, i am rich enough, while people out there see wealth only as money so that when they get sick, the money they have is used up to pay for their medical treatment.
There is a wise sentence that i once heard, written that although money is a measure of wealth, true wealth is a comfortable mind and a calm heart, That sentence is quite great imo.
Rich is defined depending on the context, the rich context in this discussion is closely related to economics and finance but I did not find your statement related to the discussion of economic standards which are included in the rich category, so let me complete your statement that rich has material wealth standards that are useful for family needs, running the business you manage, having an emergency fund for medical expenses and other needs.
Even though my economic level is not classified as rich, I am grateful to have gotten a new job to increase my monthly passive income, I have enough income for the needs of my small family and allocate some funds for emergency savings.
