help with clubs

Hi, I (22, F) just started playing golf this month at ranges a few times a week and have had a couple lessons. I’ve been using a Men’s Wilson Ultra beginner set that was gifted to me. I’ve heard that the irons are okay on those but should upgrade my driver. Would getting the TaylorMade Rocketballz 10.5 Degree Driver w Flex 45” be good? I’m not sure what those numbers mean, so any info would be useful! Thanks!
