“Don't play games that you don't understand, even if you see lots of other people making money from them”

Simplified Meaning:

You should not get involved in activities or investments you do not fully understand, even if you notice everyone around you earning a lot from them. This is similar to watching your friends play a complex card game where they are winning big, but you don't know the rules. Jumping in without knowing how to play could lead to losing all your money. Consider the stock market: many people made quick profits by investing in certain stocks they knew nothing about, just because others were doing it. But when the stocks crashed, they lost their money because they didn’t know when to sell or understand the risks involved. You should always learn about what you are getting into before taking part. This way, you can make smart choices and avoid losing what you have. In life, being well-informed helps you make better decisions and keeps you safe from potential pitfalls.
