It doesn't mean that you can't gamble if you know math and economic calculation, because gambling itself is a kind of fun for people who engage in it. This kind of fun is much higher for them than losing a few dollars or winning a few dollars.

For example, many people will buy lottery tickets, which is also a kind of "gambling" from a certain perspective. As the saying goes, it doesn't hurt to buy lottery tickets occasionally. Most people who know mathematics and economic calculation will not make careful calculations before buying lottery tickets.

And many people who know math and economic calculation will also buy futures or funds. I always think that this kind of investment and financial management similar to "gambling" depends on luck, but maybe people who know mathematics and economic calculation prefer to rely on their professional ability to get income?
