You can buy thousands of lottery tickets and it won't meaningfully impact your odds of winning though. You can also go stand outside in a field with a metal rod in your hand during a thunderstorm. "You" isn't really the point, it's the cumulative probabilities that matter. For lotteries this is easy to calculate, for lightning strikes the best you can do is probably looking at past statistics.

Right, but the population of people who buy lottery tickets often do buy more than one lottery ticket, so even if the number of people buying lottery tickets divided by the per ticket chance to win is smaller than the number of people divided by the chance of being hit by lightning, the overall chance of anyone winning the lottery can be higher than the overall chance of anyone getting hit by lightning for the same period.
