Casino table games and sports betting have the highest prevalence among gambling types. This study compared sociodemographic, behavioral, motivational, and psychological correlates between casino table gamblers and sports bettors in a clinical sample of male problem gamblers in South Korea (N = 1,459; casino table gamblers = 406; sports bettors = 1,053; M = 33.80; SD = 8.47). We assessed sociodemographics; gambling mode; legal status; gambling duration; gambling frequency in the past four weeks; total losses; problem gambling severity; gambling motives; depression; anxiety; and suicidal ideation. Sports bettors were younger (χ²(3) = 23.54, p < .001), more often unmarried (χ²(2) = 11.78, p = .003), and more highly educated (χ²(1) = 4.95, p = .026) than casino table gamblers, with no group differences in employment or debt. Sports bettors more frequently gambled online (χ²(1) = 73.37, p < .001). Gambling duration differed by gambling type such that sports betting was overrepresented at 13-120 months, whereas casino table gambling was overrepresented at ≤12 and ≥121 months (χ²(3) = 28.40, p < .001). In the past four weeks, daily participation was more common among sports bettors, whereas participation once or twice per week was more typical among casino table gamblers (χ²(4) = 25.85, p < .001). Casino table gamblers were in the ≥US$741,000 loss band (χ²(4) = 26.54, p < .001). Legal status did not differ between groups. Compared with sports bettors, casino table gamblers endorsed higher social (p < .001), avoidance (p < .001), and amusement motives (p = .020) and reported higher depression (p = .016) and anxiety (p = .006), with no group differences in problem gambling severity or suicidal ideation. Collectively, these findings suggest that casino table gamblers and sports bettors differ in ways that support tailoring clinical interventions to gambling type.
