"Coward" is a bit too strong of a word, to be honest with you.

cuz all of theas Years he did not show us only Little thing from the story and all what he do was showing us is cases and 80% of them dont Contain a thing from the story

and only 20% is what we get so what it is meaning of this ?
Let me ask you this question: What got you into Conan? Was it honestly the plot that got you hooked? I'm going to say, "I doubt it," because after 10 episodes, the plot starts to become few and far between. I realize what you're saying, but just think about what you're actually trying to say here: You're afraid that your favorite series won't have an ending. Of course it will. His other series, really, just weren't
that successful during their original runs. If they had been, he would have continued with them. Kid still lives on today, and his cases are some of the most widely regarded in all of Conan. Yaiba... Well, honestly, I've never once heard anyone complain about Yaiba not having an ending. Let's just say that, I guess.
Again, though: If these series' had been even remotely critically received as Conan is, he would have continued or ended them properly.

You sound like someone who has been scorned by a psychic after learning they're all (read: every single one) frauds. He is one of the greatest manga artists of all time, if only because he isn't doing your general take on the whole process. The Conan story is absolutely fascinating, yes, but if he had started only doing cases with true overarching plot behind them, it wouldn't have lasted ten volumes (more like three). What's great about the "story"-relevant pieces of Conan is that they only come along once in a while, and they're usually jaw dropping. The truth is, Conan is a lot like other detective series. Some will have plot-advancing episodes, while others will be your run-of-the-mill cases. To say that you just simply cannot enjoy this is to say that you do not like mysteries, really.

the meaning is the our manga artist is just coward who got lucky with the idea of (detective conan) and he want to make it long as son as possible so he can be rich
I wouldn't worry about Gosho's financial situation. He's been greatly wealthy for many, many years now. The reason he's continuing the series is because... well, the man has a story to tell, and he's going to tell it at whatever pace he likes. Serialized mysteries and other related genres simply don't operate on over-arching plots--it just isn't how it's designed.
Conan is a medium by which he tells said story, and really, that's all we can ask for.
