Fun fact, your seed phrase can generate all of my addresses if you use the proper derivation path. The number of possible derivation paths is astronomically large (as people explained above). This renders the probability of finding a collision close to 0.
But, as I said, our seed phrase, though they look (and are) orders of magnitude different, they can potentially generate the same addresses (i.e. we can steal each other's funds - in some parallel universe).
