Because it contains the weak base BrO which makes it a weak acid even though HBr is a strong acid
H2Se is the acid as it is donating H+ to H2O and forming SeH- (which is conjugate base).
H2O is the base since it’s receiving H+ from H2Se to form H3O+ (which is the conjugate acid)
Se is in the same group as O but is in different period which means Se has higher radius compred to O. this led to H-O bond being stronger than H-Se bond and H-Se bond which in turn makes it easier for H2Se to donate H to H2O
