How much time would I have to spend trading to turn a profit?
The high frequency trading you reference has no adverse impact on individual investors - at least not in the "going to take advantage of you" way that many articles imply. If anything, high-frequency trading is generally more helpful than harmful, adding liquidity to the system, although it can cause some volatility and "noise" in volume and other data, and the sudden entrance or exit of this type of trading can drive some abnormal market movements. As to research and time needed for trading, most data suggests that the less you try to "beat the market", the better you'll do.   Trade activity tends to be inversely related to returns, particularly for individuals.   Your best bet is likely to learn enough about investment risks to ensure you're comfortable with them, and invest in broadly diversified asset classes, regions, and sectors, and then mostly leave them alone, or rebalance annually.   You'll almost surely do a lot better that way than you will if you spend countless hours researching the "right" stocks to buy.
