Toliopoulos played from a young age with the youth teams of the Greek club Panionios Athens, before he started his pro career with Ikaros Chalkidas.

Toliopoulos began his professional career with the Greek League club Ikaros Chalkidas,[1] during the 2013–14 season.

On 29 June 2021, Toliopoulos signed a two-year (1+1) contract with the Greek club PAOK Thessaloniki.

On 22 April 2023, Toliopoulos moved to French 2nd Division club Boulazac Dordogne, for the remainder of the 2022–23 season.

In the final group stage game against Australia, where the national team won and qualified for the knockout stage of the tournament, he was less prolific from the three point line, but still proved to be extremely helpful for the national team, by scoring 14 points, all in crucial moments.

Toliopoulos' childhood idol was the former Greek basketball player Vassilis Spanoulis[7] and his style of play perfectly captures that.
