Distinct Count Two Measures

Here's what the measures should look like:

[Follow up] =
COUNTROWS(
    FILTER(
        VALUES( Assessment[User ID] ),
        CALCULATE(
            DISTINCTCOUNT( Assessment[assessment_id] ) >= 2
        )
    )
)

 
[Total Users Training] =
CALCULATE(
    DISTINCTCOUNT( 'Sessions'[User ID] ),
    KEEPFILTERS( 'Sessions'[Event Category] = "Training" )
)

[Users in Both] =
var FollowUpUsers =
    FILTER(
        VALUES( Assessment[User ID] ),
        CALCULATE(
            DISTINCTCOUNT( Assessment[assessment_id] ) >= 2
        )
    )
var TotalUsersTrainingUsers =
    CALCULATETABLE(
        DISTINCT( 'Sessions'[User ID] ),
        KEEPFILTERS( 'Sessions'[Event Category] = "Training" )
    )
var Result =
    COUNTROWS(
        INTERSECT(
            FollowUpUsers,
            TotalUsersTrainingUsers
        )
    )
RETURN
    Result
