Of course, this is not necessarily, it depends on the project. For example, tennis, the Olympic Games is basically an amateur competition, many big names will not participate, but the grand slam is the most important (tennis has no concept of world championships). For most sports, the Olympic Games and the World Championships are the highest level competitions, which are comparable. However, because most of the World Championships are held once every two years or once a year, and the Olympic Games are held once every four years, there are few opportunities. So under normal circumstances, Olympic athletes will work harder. It is generally believed that the qualification for winning the Olympic Games is a test. For example, table tennis and basketball are all the same Take basketball as an example, the Olympic selection qualification of men's basketball team is the second place in Oceania Championship, 2-3 places in Africa Cup, 2-3 places in Asian Championship, 3-5 places in American Championship and 3-6 places in European Championship.
A few months before the start of the men's basketball Olympic qualifiers, the specific schedule will be determined before the teams draw lots. As for who the opponents are, judging by the previous sessions, there should be teams from Puerto Rico, Canada, Italy, New Zealand and Greece. Most of the qualifiers are strong teams from Europe. If China can't win the Asian Championship, it will be very difficult to enter the Olympic Games through the qualifiers. In short, it is very troublesome to divide the events.
