Pretty much correct. You will need to show either sufficient money in the bank or from external sources (pension, retirement funds, income derived from another country), or arrange a job. Generally if you can land a job with a foreign employer they get a work permit/work visa for you. You can’t just show up and start looking for a job. How expensive and difficult this can get depends on the destination country, your citizenship, your assets and income, and sometimes your education and skills. Some visas have age requirements, either 55+ (or older) for retirement, or much younger for student or skilled worker. The other common path is marrying a foreign national. The USA has these same rules. When someone comes into the US on a tourist or student visa, or no visa, then tries to get a job, or works under the table, they are breaking the law and can get jailed and deported if caught.
