First, this is not a strategy, it's rather a deed/decision, you do not need to make a serious analysis before you repurchase cheap lottery tickets. And by repurchasing, as used in this context, it means you've won before, and if we win in this kind of lottery, it's like hitting the jackpot, so there will be more money to retry your luck if you win.

I read of a guy who won millions in 2021 and won again in 2024 just by retrying with a small amount. This guy also invested the money and became a CEO with it. This suggests that good use of the money matters and even if we repurchase, it can no longer hurt us unless we've never won before and desperately playing it.
