Will it be better than fortune telling after converting to Buddhism?

It doesn't have to be like this. After converting to Buddhism, it can only show that you have started to believe in Buddhism and are a Buddhist believer. It doesn't change your destiny. What can really change your destiny is to become a yogi after being ordained.

Buddhist practitioners deepen their practice by knowing cause and effect, knowing good and evil, breaking evil and cultivating good. Breaking evil will reduce troubles and pains, while practicing good will increase a person's wealth and wealth. This will change your destiny for the better.
