In any case financial management is a key pillar for achieving goals and it's fundamental to life. It may seem simple but many people don't practice it. So don't underestimate financial management in trading.
In trading besides money management you also need risk management. Money management means being able to manage your money in trading, at least with money you can afford to lose. Risk management, on the other hand, requires knowing how to avoid risks beyond your control (such as news, black swan events, etc.). Furthermore, you need to have analytical skills when trading, such as understanding market movements and potential trends.
Risk management will also involve money management in it's okay. Risk management teaches us how much of our capital should we risk on once specific trade. Risk management according to me is a key factor to really have profits without much losses in trading. Trading will defiantly give us losses as no one has that "perfect" strategy. Everyone will end up in loss atleast a couple of times before starting a winning streak. But how to minimize those losses, how to recover from those and how to end up being profitable even after bearing losses is what risk management teaches us.
For a beginner, learning how to trade and using different indicators as well as a proper understanding of risk management can be a good start. Experience will teach the remaining.
