When it comes to wealth creation in equity market, investing and trading are the two genres of the field. However, investing and trading are very different approaches of wealth creation or generating profits in the financial market. In daytrading you avoid the possibility of huge overnight losses, you can go heavier, but your % of winning will be lower, fees will have an higher impact on your profit because you will trade more frequently, you have a smaller edge against algos and it can be frustrating because in certain day nothing will move or nothing will have a predictable way of moving so you can't make money off that thing. Daytrading is the most profitable in case you have an iron discipline, you have the 8hours to trade (even though most of the action is in the first 2  and in the last 2 hours), and your bankroll is big enough to make your risk per trade big enough to overcome the fees.
Investing, you have to allocate your money as best as you can and you don't have to bother of daily flucutation or to temporary downtrend in the s&p or whatever benchmark refers to your positions. The important thing is to make the right picks over the long term, it's important to establish a thesis for being long a stock and keep it that way.
