You are lucky, don't think otherwise and slots machines are all the same it doesn't matter if the locations are different or they look different, between I am glad you are able to win, because risking $100 on slots in a single day is way too out of my league lol. Many people walked away from slots because they keep losing and losing over again, I have two friends that quit slots and focus on sport bets only, I guess they want that win not too far away, unlike myself that don't care much because I have free little amounts to spare.
Some slot games from different casino varies since they do adjust their slot RTP depending on the owner preference. This is applicable on physical casino although there’s some online slot providers that allow changes on RTP based on the casino desired RTP setup.
But in general for physical casino choosing where to play slot game matter because of the RTP.
