Today I asked someone, who has been trading the stock markets for years if day trading is still profitable for a newbie trader in 2020. He told me that day trading is dead for human beings and automated trading is taking over and I should not waste my time with it.
What makes this person the authority on the future of trading? Perhaps he's projecting his own failings as a trader? In addition, automated trading is not taking over and ruling the market. And high frequency trading is responsible for a significant amount of daily volume but that's not displacing traders. There's money to be made every day in a plethora of ways.
Day trading is and will always be profitable for those that have the education and experience. But let's be realistic. In order to live off of it, you need to be heavily capitalized and be able to not only withstand losing years but to be able to withstand withdrawing post tax dollars every year for living expenses. I'd offer that those who have spent a career in the investment sector (brokers, market makers, floor traders, etc.) would be among the few who could readily do this - not the Average Joe.
OTOH, it is reasonable to expect that once you have sufficient assets and years of experience, you can augment your income with some day or swing trading. In most years, you're not going to beat the market, let alone come close matching it. But that's not the goal.
Keep your day job, save and invest. Take care of your future. At the same time, become financially literate. At some point down the road, take an amount of money that you can afford to lose and focus on disciplined risk management. AI isn't your enemy. You are. See if you can trade for a year and not lose it. Achieve that and you could quite possibly be on the way to earning some supplemental income.
