In my opinion, both sports betting and slots are equally addictive. In slots, you are looking for a strategy on how to hit the jackpot by manipulating the bet or going through the slots, and in sports events, it is a search for insider information about the match you want to bet on, plus dealing with team scales, player injuries, and so on. In both cases, you need to have a sober head so as not to turn the game into an addiction.
Gambling addiction has nothing to with the specific games you put your money on. Gambling has this spirit of making you feel you can double your money, it will tell you to risk Y amount to make an X amount but then you aren't sure how possible it is. If you do it with sense, you might make it and you might not make anything but if you make nothing out of it and you were able to stomach it, then you have nothing to worry in the future but if you want to forcefully recover the money that you lost, you might end up addicted faster than you think.
Whether it's sport bets, casino games or crypto games, online or physical games, if you do them too much, you will feel the effect very well. In fact, if there is anything you do in this life and you go extreme about it, you will reach a point of marginal satisfaction where the positive side will turn to a bad side.
