Samuelson, who excelled as a three-point shooter, qualified twice for the NCAA final Four, in her freshman year of 2013, and later as a senior in 2017, where she had been a Regional All-Tournament Team before losing the semifinal with a sprained ankle.

[3][4] She went undrafted in the 2017 WNBA draft,[5] and joined the Los Angeles Sparks for the 2017 season and played 3 pre-season games, but a fractured left foot suffered during training camp led the team to waive her.

While Samuelson left after four games due to the return of starter Jantel Lavender, the Sparks eventually brought her back for the rest of the season in June.

After being waived during the Sparks training camp,[12] Samuelson joined them late in the 2019 WNBA season, following her performance in the EuroBasket Women 2019.

[25] During the 2023–24 EuroCup Women, Samuelson was chosen as the tournament's top player for February 2024 by leading the Lions in their quarterfinals victory over Melikgazi Kayseri scoring 44 points and shooting almost 63 percent in both games.

[30] In November, Samuelson helped the British team win the final two games, granting them a spot in EuroBasket Women 2019.

[31] During the European tournament, Samuelson averaged 11.1 points, 4.4 assists and 2.9 rebounds as the British team finished in fourth place.
