Yes - only the budget bill is not subject to cloture (i.e., done through ‘reconciliation’). The reason is that the budget, while law, is considered ministerial, or, the actual functioning of government. All other laws, are ‘simply’ laws; thus subject to the regular rules.
That’s why taking healthcare to reconciliation (attaching it to the budget, as was discussed last fall if they were going to pass it by August) was so toxic.
Is that your understanding?
