How are you guys judging your strengths based on LC count?

I see many posts over here with comments like this .. ‘’ I have completed/solved <insert number> Leetcode count. Will/Is that be enough for <insert company> interview. ‘’ I just want to know that don’t you guys judge how much problems you’ve solved or how much grasp do you have on each topic/concept. (Topic here being : Trees, graphs, LL and other common algorithms and DS) Is there a significant count that leads to this?

Additionally, does solving questions on LC contests compare to how a person would do in an interview? It’s an environment of facing new problems (just like an interview)
