If anyone don't understand this basic thing such as budgeting then they should not be in business or have anything to do with finance. OP you did a good job but have honestly post like this are basic, this type of post will have a good fitting for beginners and help. This is a vast forum and the economy board of the forum talking about very basic thing like this that is obvious as day light is a bit cringe.
However, budgeting can be learned if there is willingness to learn. So I don't see any reason that it will be a barrier if you want to build a business or anything that pertains to money management. Real-life experiences will serve as the best teacher, and your own mistakes at first will leave you a big lesson on how important budgeting is, and how it should be done properly and organized.
Nobody has a monopoly if knowledge, what you don't know can be learned from others that have experiences in the area, so budgeting can be learned inorder not to spend unwisely. In this generation you don't need to go to school or enroll in a course to learn about budgeting, AI and Google can give you answers and share links that can help you to learn. It is not necessary to understand the importance of budgeting from your own mistakes because you can go bankrupt and be in dept before you understand. Increase your knowledge about budgeting from other people's successes or mistakes, also take advantage of the internet to learn.
