Yes, the market demands sacrifice but not as much as you iterated it above. Naturally, you will sacrifice your time and money for trading, especially when you are in the learning process. But as you get more experienced in it, your money should be giving you more money and the time you need for trading would have reduced drastically. Except for those who are scalping or using the low timeframes, still, they would have mastered their trading strategies and know the time to trade and the time to do other things in life. Therefore, there is no big deal here.
