I took this reading from my fish tank what does it mean what do I need to change.

I just got a betta fish. I didn’t do it correctly I was u def the impression you just need a bowl and water and fish. I didn’t realize how much went into it. I didn’t cycle my tank I just put the fish in it was for my kids. But the more research I do the more I try to make sure the fish is properly taken care of. I got a filter a heater a thermometer a light and I just recently learned about the nitrogen cycle and am aware of water changes 25-50% every day until it gets settled.

I took this test to check the water and some results are obvious where it says safe and dangerous but some of them I don’t understand. Can anyone give me tips of what I need to improve please I really want to keep it alive I know I need a bigger tank this is what the pet store people told me was for this fish
