If you trade with emotions so yeah, trading and gambling are the same. But if you know the basics, you understand the only mutual thing is the risk.
You can use analysis for both but as you've said that if someone doesn't do that and is mostly doing things according to his emotion then you're right that there's no actual difference.
Personally, I consider trading a more legitimate and safer activity than gambling, which can be associated with addiction and other negative consequences. They may have similarities, but the differences between the two are significant. Either way, it is important to understand these differences before getting involved in either activity.
We've got the same thought about trading as a safer thing than gambling. You know that in gambling, at most times it will trigger you to lose your emotion. While in trading, it's always giving you a reminder that you shouldn't do that with your trades as if it's a very serious matter to be taken.
