That is honestly up to you. You can very well try that, but it would be a lot more likely if you were to just create a spell for you to bring more wealth into your life. Focusing on winning the lottery is a long shot, think about this for instance, if you are focusing on winning the lottery, how many others are doing the same? So I would suggest making a spell to attract more luck and wealth into your life, that could be more beneficial to you. I would also like to point out though, that magick is not a quick fix, it would be a good practice for you to work towards getting more money and luck into your life even if you create said spell. Two forces working towards one goal has a much better outcome.
