No, you
1) insert *two* values: 1 and (SELECT) expression;
2) improperly use (SELECT) expression:
There are no array type in sqlite. Only single column results is allowed for
(SELECT) expression, e.g.:
sqlite> SELECT (SELECT 1,2);
Error: only a single result allowed for a SELECT that is part of an expression
Just only first discovered error can be returned (and in this case it was
inconsistent number of columns for insert).

Correct:
INSERT INTO leagueplayers (id, playerid, value, currvalue)
SELECT 1, playerid,value,currvalue FROM players;
