Do mice return to peoples houses?

i found a mouse in my house this morning, i caught it in a box and i took it outside what are the chances of it returning. p.s. i didnt put it in my yard i put it in the street and watched it as it walked across the street to the next lawn. also i had some poison pellets out and im thinking thats why the mouse came out and revealed itself i thought it was strange that the mouse just walked out in front of me in plan sight and it didnt seem scared i assumed it was sick could i be right.
