In summary when you have everything you need to survive and you don't need money, are you poor?
Someone with background in finances will tell you that it's a lack of money, someone with a degree in economics will say it's a lack of resources to satisfy basic needs, I say it's lack of knowledge, skill and opportunities.
You don't need money, but you either need skill, so that you can steal or persuade other people to give you what you need, or you need an opportunity.
I've earned a lot of money through an opportunity because someone told me to research bitcoin and I did, got hooked and it became the best investment of my life. I know people who are wealthy because, for instance, they married into a wealthy family - which again is skill and opportunity combined.
Poverty is the inability to provide yourself money and resources that you need to sustain your life and keep you living. However, know that poverty is not a hindrance to see yourself from going up. As long as you have the life’s strategies and the right attitude that you need to conquer poverty, then you can always take advantage of every opportunity that mostly only rich people gained. But if you chose to stay poor and not taking any progress, then consider yourself living in poverty for long.
