do the different strains on carts mean anything?

Title may be a bit shitty, so let me elaborate: I got a couple carts from Trehouse, one labeled as gelato and another as green crack, i noticed the website talking about the differences in effects of these two “strains” and it made me wonder, is this all bullshit? do these carts just do the same thing with different flavors, since they’re not actually bud? i’m new to cannabis in general so be easy on me 😅
