It seems to me that there should not be all faith or disbelief, here you should go to the exact understanding of what you can earn, and if you choose a broker, such as Amarkets, then the conditions will be favorable for both you and the broker.
I was greatly helped by the training materials that are provided on the website of the Amarkets broker, as well as by the managers who helped me navigate and choose what suits me.
It seems to me that I am sure of being lost due to fear and inexperience, which is why they believed that practice on a demo account gives a good enough strength base to be confident in real trading and the Amarkets broker offers a very good option.
