"ربما كنت سأكون مشهورة حتى لو لم أكن كورتني كارداشيان."

Simplified Meaning:

Kourtney Kardashian is saying that she believes she would be well-known even if she didn’t have her current famous last name. It's like how some people feel confident that they have unique qualities or talents that would shine through no matter what. Think of someone who is very good at drawing. Even if their parents aren't famous artists, their talent would still get noticed by others. In life, this means that believing in your own abilities and uniqueness can help you stand out. Just like how a great chef might become popular because of their amazing cooking, regardless of whether their parents were well-known chefs. Kourtney is emphasizing that she's confident in her own value and abilities, not just her family's fame. So, if you have a special skill or a great personality, trust that it can bring you success too, regardless of where you come from.
