No.
. ./my_script.kshexecutes the script within your current (probably login) shell.
sh my_script.ksh creates a new shell in a child process and executes within that. Neither of them obeys the shebang (#!) in the script.
sh my_script.kshis roughly equivalent to
./my_script.ksh, but only if the shebang specifies /bin/sh as the executing shell.
