Concentrate on doing your undergraduate degree first and doing the best you can. With that you can pursue any kind of psychology afterwards.
As for the difference between clinical and counselling there are some (mainly about the way they are trained and the focus), but on a day to day basis, many clinical and counselling psychologists will work in mental health services delivering therapies, supervising staff and working with service users to help overcome their difficulties. The best thing you can do is try to contact some real life counselling and clinical psychologists who are willing to talk about their work.
For me (clinical), a day in my diary last week was:
9-10am: Team meeting -discuss the teams caseload and pick up any high risk issues.
10-11am: Therapy with someone suffering from severe depression
11-12:30: Going out with the team's psychiatrist for a home visit.
1pm-3pm: Running a CBT group around anxiety.
3pm: Supervising one of the support workers.
3:30-4: admin, write up notes.
4pm-5pm Therapy with someone suffering from an eating disorder
Days are quite different though. Sometimes I may have to do some training and have my own supervision. Or other days there may be more one to one therapy and no group, or I may have a longer assessment slot. Thats just in adult mental health, and it will be different in child, older adult, forensic etc.
