Can you please mention the topic of your essay?
Yes, msarkar is right. You should always do that as it gives us an opportunity to understand what your prompt requires from you.
Topic: Nowadays celebrities are more famous for their glamour and wealth than for their achievements and this sets a bad example for young people.
To what extent to you agree or disagree with this statement?
...Here it is :)
Now let's have a look at your first sentence;
Some people argue that adolescents are being influenced badly by untalented people who become famous thanks to their luxurious lifestyle and wealth.
Here you do not categorically refer to the celebrities. All famous people are not celebrities and your prompt specifically talks about the celebrities. You need to stay aligned with the prompt throughout your writing :)
