Assuming the statistic you provided is correct, one in every 20 chanseys has a lucky egg. However, you can’t catch a certain number to guarentee that you will get one; even if you encounter 20 pokemon it does not guarentee that one of them has a luckey egg, that just is how likley it is that one of them has it. Each encounter has a fresh chance of having a lucky egg; it doesn’t become progressivly more likley.

Thus, I would recommend that you use a pokemon with the abilityfriskto see if the chansey is in fact holding a lucky egg because there is no real other way to tell and you’ll be draining your resources catching that many chanseys in hope of finding one with a lucky egg.

As the other commenter noted, you can never guarantee a lucky egg even with 1000 chansey.

However, what I imagine you want to know is how many chansey do you have to catch to receive a lucky eggon average. The answer is14 chansey. This is because (19/20)^14 is less than 0.5. Therefore, the odds of rolling fourteen 19/20’s is less than 50% to happen.
