To invest in something means to pay money to buy something that you expect to go up in value or provide an income of money over time. People invest in stocks, bonds, real estate, precious metal, and collectible items such as paintings or even dolls. Some investments are relatively safe that you are sure you get your money back and some amount of additional money and other things are risky where you can lose the money.
In general, the higher the risk of loss, the higher the money back you would expect if it goes well.
It takes time to learn about investments, and most people who are rich make or made money by investing it, but some people who were rich become poor by bad investing.
Here, for example, is a gold price history for the value of 1 troy ounce of gold in US dollars:

This is the Dow Jones Industrial Average, which is a set of stocks over time

If you notice, the value goes up and down.
Bank CDs and savings accounts pay very little in interest, but are safe.
The longer you have in time, the more you can allow for ups and downs, where the general trend is usually up. Investing is gambling, and you need to be able to afford to not have the money you invest and allow time to hope it rises in value.

Your question states that you are not fully ready for investing
Do not go for the quick buck. We serious investor have a saving
Bulls make money

Pigs get slaughter
Invest for the long term to create long term wealth. Use dollar cost average and ignore short term market news.
