"I don't have" and "I have no" Are both grammatically correct? Can I use both in the same context? Thanks for your help!

Who deserve it? When I think about opportunities I've always asked myself if all all the people around the world have them in the same way. It's not the same thing to be born in USA, Canada, European Union, Australia, or the UK than in Latin America, Africa or other countries in Asia. All of us know that in the last three Continents things can be a little bit harder than in the others. The economical, social and political situation make a big difference when we talk about human development. I've known a lot people from developed countries, and most of them who has been in Latin America or Africa has a lot of complains about the situation in those countries but just a few has thought why people over there are in that difficult situations. In Latin America, for example, we've been victims since years for bad governments which hasn't made good advances for a well growth, corruption has been one of the worse cases that has affected our economical and social situation, therefore most of Latin people don't believe in politicians because in the past and in the present we've realized that at the end they just have looked for their personal interest. Nowadays we can see how international cooperation is giving lots of aids in developing countries but sometimes it seems like is not working, so that's the moment when we ask our self if behind of those good intentions are other things which we cannot see. The big questions is, how many years further people in developing countries have to keep waiting to get the same opportunities?. Emigrations it's one of the consequences that we can see in this days, we have a lot of people leaving their countries with the hope to find better chances, and I'm pretty sure that no one of them like that but at the end everyone is looking for the best for their families, and lots of them are getting ready to get the challenge even if there are indignity situations to face. Free political is the key that we need to face this sort of situations, governments have to find better agreements to set fair social policies, and power countries must to support those initiatives without looking for economical interest because wellness is a right that every single human being deserve it.

Is it possible to use "in fact" and "indeed" in the same context? I know the meaning of both expressions but I do not know if it depends of the context to use them, so does it matter or not? Note: if you find any mistakes in the question structure or in any other sentence please make the correction too.

When I was living in Africa Africa, the only thing I knew about Africa was what I had seen in movies and news. I imagined that every thing was bad in those countries, in fact when I took the decision to go, all of my relatives and friends told me that I was crazy, arguments as "it's a dangerous place, you should think better, you shouldn't go", etc. At the end I went there, specifically Rwanda, such a nice place, a small country with a lot of needs but with amazing people, very polite, friendly, all the time trying to make you feel good. I was very surprised how that safety is that place, you cannot imagine, for example in Kigali, the main city, you can walk around at any time and nobody will rob you, I couldn't believe it when I was walking by the street at 11 o'clock pm and every thing was good, I did it for more than twice. As a tourist I got the opportunity to know two other countries, Tanzania and Kenya, both are nice places. The first has the best safari you can do, I did it and it was one of the best experiences I've ever had. In the second I just could visit Nairobi, its main city, is a big one I really liked it. It's kind chaotic because of the traffic but if you like to walk you can see it in a better way. With my experience living in Africa I learnt that we shouldn't let to be influenced for all the things that we just hear, is better if we find more information because all we see in the TV and news is not the true.
